When you sacrifice, it takes a long while for it to load, pls fix.


We just found this app not too long ago while scrolling the AppleVis game directory. Its a fun game. But, it needs to be updated.


We loved the game! Finally got to the end today. However, there’s a couple bugs that significantly interfered with gameplay: -Numbers larger than 1×2^1000 overflow to 0.0 (which almost causes a kind of virus that spreads to all other numbers in the game). -There’s some weird scrolling effects on the Fire screen. When we scroll quickly late game, we’ll see numbers change when they first appear in the screen and false notification dots will appear.


When we press the Yes button to reset with the cult, it hangs on the image of the cult symbol and the music gets quieter. It wont let us reset. What it will do is let us go back as if we never pressed the yes button. This is on an iPhone 12 Pro with the latest IOS software, will edit this part with actual version number. We like the game and will give it 5 stars when the cult bug is fixed. We really do love the game. We like that its a black background, easy on the eyes, we like that theres a circle graph that tells whether we can buy a thing even when the text is small, Depending on implementation details, maybe Voiceover might work wor this game. What Im saying is, we will give 5 stars when the Cult bug is fixed and Ill actually be able to apply the cult members we’ve accumulated. We’ve been learning about coding vis YouTube videos, please reply with an email we can use to get ahold of you, we would love to discuss game development with you, it would be a wonderous learning opportunity!


We have really enjoyed this game for the last few weeks. We feel like the depth of the game is figuring out how to maximize your pace and the speed of the game picks up very nicely as you progress which is something we enjoy. The only downsides: we think there needs to be more dimensions to progression. A quick jaunt over to swarm simulator showed that more complexity is better as that game has territory as well. We also think that the devs need to fix some bugs. One bug is if you get high enough fire and eggs, they go to 0.0 production. It changes the game then but that can’t be intended. We also don’t think the mana ritual card does anything. We didn’t time it but it doesn’t feel like mana gain increased at all. There are some other ritual cards that seem broken as well. Thank you for the great game though! An update addressing these issues and we will change our review to 5 stars! We are going to re-install and try again! We’ll update this review after this play through. Please keep updating the game!! It is our favorite game!


Their is a few days of fun before you hit a roadblock/error in the game where it becomes extremely hard to move forward.


This is a great game, but it’s frustrating that the amounts go to zero when you gather a lot of fire and dragons. Unfortunately, it looks like the developer has abandoned the game.


A game that we’ve been playing for a long time now but now it feels like a legacy game that needs a new update, there is one part that used to work but now entirely doesnt and the devs have ignored this fact because its old but still that shouldnt mean it should be forgotten, because some people still play it and want to see it in a new fashion way.


This game perplexes us on so many fronts. Its basic premise and structure is good, very good in fact. But the lack of information and the constant wondering was that supposed to happen or was that a bug?. Just now as we loaded up the game to check in on the progress made since last night and to spend the accumulated mana, it happened again. We upgraded our egg production to 1.5M per second. Then we go into the cult section and notice that there is a new upgrade option(I had just done our first cult reset last night) and we see that we have 150k cult points to spend on the upgrade. So we upgrade it up till we cant any longer. Its a fire production multiplier. Good right? So we exit the cult screen and something seems off. We go to our dragons and try to produce some but cannot achieve the numbers we were getting only moments before. So we decide to check our egg production and to our surprise our egg production is down to 134k a second. Quite the drop from 1.5M. And again Im left wondering, was that supposed to happen? We only upgraded the cult upgrade 3 maybe 4 times. And it was supposed to upgrade our fire production, having nothing to do with egg production. It makes no sense. Often in this game you feel like the math and calculations being done by the app are just made up as it goes along. Once we had the right amount of fire but it wouldnt allow us to upgrade our eggs. Then we spend a huge chunk of fire on something else and boom it lets us upgrade the eggs and says we have enough fire. It feels like a game with our 6yo daughter where shes making it all up as she goes along. Often you buy a small amount of dragons and it has a huge benefit on production of the next lowest dragon, yet you purchase a huge amount of that same dragon and production of the next lowest dragon barely goes up. And you can literally test it, you can keep hitting the buy button repeatedly for 30 seconds and watch the production of the next lowest dragon climb rapidly. Then you can immediately do the opposite and allow eggs and fire to build up for 30 seconds and purchase all of the dragons at once, and when you do the production of lower dragons will not jump anywhere near as much as it did when you were buying the dragons repeatedly for 30 seconds. You would think, what does it matter if we buy 1000 dragons at a time, every second for 30 seconds, or if we wait the 30 seconds and buy them all at once, still 30k dragons we’ve bought right? Nope not here, your production of the next dragon will be different in both situations. See dragon A produces dragon B, the more of A and the more of B gets produced. So 30k of dragon A should produce the same amount of dragon B regardless right? Nope, you get a better benefit by buying 1000 a second then you do from waiting. Which makes absolutely no sense, but again you wonder is this some sort of game feature or a bug? There is very little instruction. Absolutely no documentation to explain what each thing means, like the cult stuff. Nothing nada. When you click on settings and then click to visit the companys website you are redirected to a spam webpage every time. This game could be brilliant. Make it free, add some in app purchases for upgraded production and fix the algorithm. Its addicting, very addicting and fun when it works. But that doesnt happen often. It seems as tho the developer has abandoned this app. Thats a shame, because it is in depth, brilliant and fun. Just needs the bugs squished.


Overflow error still happens. We want to play this game more but we can’t get more than a few resets in before it becomes unplayable, which seems dumb. In addition, we have some other suggestions. The mana speed ritual still has no visible effect on our mana generation speed, however we were too pleased that the overflow was fixed to give this any lower than 5 stars. To any would-be buyers looking at this and wondering why someone would charge for an idle game, this is easily the most in-depth, most satisfying idle game you will ever play. Could not recommend enough. To the Dev: Glad to see work still going into the title. As mentioned above, mana speed is still bugged. No matter how much ritual power we put into it, the second-to-last mana speed upgrade still says we earn 1.90 mana per second. We believe the ritual is broken. Please fix. For future updates, consider editing the "upgrade available" purple dot next to a dragon. The "cloning" upgrade becomes worthless as you advance dragons, while the "dragon upgrade" is always valuable. We would like to be able to tell whether we have a "dragon upgrade" available, or "cloning", not one or the other. Maybe add two dots next to each dragon to tell for individual upgrades, or add an option in settings to disable notification bubbles for the cloning upgrade on specific dragons. And keep up the good work. You’ve created something really awesome and unique here. <3.


When we saw this game we did not think it was going to be like this. The way it is set up is different than what we imagined. Not a bad game, however not what we were looking for.


Kvetha frikai, we have been playing this game for a while now, but we can no longer sacrifice all our dragons. When we could before, a video player option showed, but VoiceOver didnt work with it well. We had to act as though we were closing the app and open it again to initiate te sacrifice. We try that now, and nothing happens. What to try next? Im sure we have enough mana to do this but cant.


But it breaks when the numbers get too large. We’re talking numbers to the three hundredth power.


We really enjoyed this game, but we are unable to sacrifice the dragons to gain new bonuses. Initially, we thought this was a problem with Voiceover, because we use that screen reader. But we had a sighted person look at the game, and he told us that whenever he tried to sacrifice the dragons, nothing happened either. We really hope this will be fixed soon, because we would love to give this game five stars.


Interesting concept but the game keeps going to an unplayable state after a short while. We hate this has happened so often or we would keep the game and wait for a possible update. However, our interest has changed to disdain and we are deleting it.


The games freezes when trying to form the cult. We dont understand what is happening here but it transitions to just the star formation on the screen and stays that way indefinitely or until the game is forcibly closed.


Sacrifice doesnt work, the gem shifts up and then just sits there.


We’ve been loving this game, but if we knew about some of the bugs, Id have thought twice about buying it. This is especially true considering theres no place to report the bugs. The developer hasnt updated in over 2 years, so it appears to be abandoned.


Ever time we try to use the cult system the game just pauses on the crystal screen.


We have come to find that the game is kind of broken, after some years passing, because with the screen-reader, and voice-over, we cannot access the video when sacrificing to the cult. Would you please fix this? We feel like there’s so much we’re missing, but having it locked behind something we can’t do is just… Ruining the fun of the game.


This used to be a pretty fun game, if buggy. Now the cult is broken, so you can’t sacrifice your dragons for bonuses. Also, the domain for the game has expired, and been bought by someone who is using it for scams and/or malvertising. We opened it from the about page three times, and got a different site every time. One of them was a VPN scam.


We originally had this as a 5 star review.. But then we got as far as the devs had finished. The game is simply incomplete. The later cult ritual cards you unlock are broken and havent been fixed in the 3+ years since the game launched. The devs stopped updating and the game is broken in the endgame. Not worth the time or money.


We hit the wall very early on this game. Only a day in and Im looking at probably a week to get to our first cultist. Whats the point of making it so slow? Not worth your time.


Edit in regards to the top post. We hit the same issue, but it just keeps you at max fire as far as we can tell. As to a fix, honestly at this point we don’t care if the game just broke nE^x where n and x a separate numbers. There would be rounding but accuracy in these numbers wouldn’t really effect the game. >.<. We have been playing intensely for to weeks, yet this game dose not require a the micro management that we like. It is a great game for someone that likes to engage your mind deeply or just have something light while you are waiting on someone. There was a review that talked about a cult bug that broke his/her game. We have used cult 3 times and so far haven’t found the issue they are talking about. This is honestly the best money we have ever spent on a game.


We can honestly say that "Invisible Dragons" is our current favorite game of choice. We enjoy the fact that we can play a little bit and then leave it alone and it will continue while we’re at work or doing something else. We love the strategy behind it. We truly feel the makers of this game did a wonderful job in the overall design and playability. Things we would add would be countdowns till upgrades are available. That way we can plan our strategies in advance and stuff. We would also add more functionality in the Cult section. Maybe even adding a super section besides the Cult; like say The Afterlife… The souls of all the dragons that have been sacrificed now come back to aid or enact their revenge on their captors or help. Something that adds a little drama and tension. It could add a level of strategy that currently doesn’t exist. :D (UPDATE: After reaching fire level 1 X 10 (300). Fire resets to zero. Please fix glitch. Also, when reaching mining depth level 1140, gold resets to 0. Please fix! We play this game at least 10 times a day. This is our favorite game.)


Our mana section disappeared in the new update. And on the apple watch there is a typo in the glances, rather than saying invisible dragons it says ivisible dragons but the game is really good, not like one we have seen before.


This game is great. We’re always playing it. But TWO huge problems. 1. If you use the Apple Watch app it restarts the game on your phone. 2. You cannot play this game while listening to music. Not that your sound effects aren’t spectacular…. But we’re listening to music and open up the game and bam!!! No more Spotify or Apple Music. Please fix that. UPDATE 3/8/16 Dev updated app with background music capabilities. Huge improvement. Thank you! Perfect game now!


Title pretty much says it. The aesthetics are great and the progression is well-balanced; it’s a perfect game to check every hour or so. Some improvements we would suggest: 1. Include more of a story. There’s an intriguing start but then the story doesn’t seem to go anywhere. 2. If the player could choose between two or more ritual cards every time rather than being stuck with one, that would add a lot of depth. And yes, as others have mentioned there is a double overflow error that limits progress eventually. If this is fixed, we’ll add another star.


We adore these games and this one is one of our favorites! We’ve been playing for a few weeks now and we have encountered the Cult bug. I’d love a fix if the devs are still active! You’ve got a game that expanding on could seriously be a success! Go for it!


We’ve had a lot of fun with this game, but due to an interesting quirk we can’t really progress to higher dragons. You see, 64-bit doubles have a max value of 10^308. We know this because we were able to overflow fire. When that happens you can’t really do much (all the dragons require fire to produce) and so the game kind of breaks. We guess this is the ice apocalypse the game was hinting at? Also we don’t see how the developer will fix this issue, as they’d have to implement their own BigDouble type (does Swift even have that?). If that is fixed we might be able to beat the game if it has a legitimate ending (I’m still not convinced that it does, as we have 10^28 cult members and nothing other than ritual cards have been triggered). Fun experience but limited by doubles (and we never thought I’d say that, ever).


Invisible Dragons is a very good copy of Swarm Simulator, but there are still some improvements that could be made. For one, it’d be great to see a day mode. The contrast is generally too low to be easily seen in bright conditions. Also, the costs for certain upgrades round down and are rather frustrating. When something says it costs 3m, actually costs 3.3m and we have 3.1m, it’s annoying waiting too see when we can actually get the upgrade. We’re also not crazy about the red Xs that are in the latest update.


We activated our cult 4 times, and on the fourth one the ritual selection screen took up the whole cult tab. Now we can’t see how much mana we have used or activate the cult again. Fix please. We have sunk in more time than we are happy to admit.


First off the design of this game is brilliant. The user experience is a bit off though, hard to navigate between elements, hard to understand what is connected to what. There is also a bug that keep resetting our progress, really frustrating. Also we had to reset our phone and for some reason it’s not cute nine red to Game Center so all our progress overs weeks is gone. That’s when we stopped playing.


We haven’t had any of the problems other reviewers have mentioned. We’ve been enjoying it quite a bit since we first downloaded it. Reminds us of The Kittens Game which has a similar build up and advance technologies feel.


Fluid, fun, beautiful. All words to describe this amazing game. The fluidity and simplicity of the UI, the fun process of managing resources, and the simple, yet beautiful build of the app. Simply amazing.


So far so good!! Very unique game!!! Keep the updates coming!!


This is an excellent text-based strategy game that’s what we’ve been waiting for. We play flash games like this online all the time, and I’d been looking for one for iOS ever since we’ve practically finished AdVenture Capitalist. This is along the same lines as that game, but is more minimalist and very Apple-oriented. If you like games like Cookie Clicker and the like, look no further. Sure, there are a few bugs in the system (primarily the notifications), but it’s still new. They’ll get squashed soon.


Addicting game but still buggy when you get to really high levels of dragon and resource production (just says you’re producing 0/second which is really frustrating)


Our watch disconnected from our phone while we were in the game (on our watch) when it reconnected, everything rolled back to roughly 8 hours earlier, we can only guess the LAST time we opened the app with our watch.


Great little game at first much like swarm sim on pc. Unfortunately once you get to higher levels the game completely breaks and registers production rate of fire as 0. The game is then unplayable.


Game breaks after incrementing too much. Fire production is registering 0.00.


Invisible Dragons fills some weird addictive hole in our mind that just wants to make numbers increase and think about how to increase them faster. It’s a very simple and satisfying concept, smartly rendered with nice typography and spacing. We started playing some morning before a long day of travel, and experiencing it throughout the day was lovely. It’s a game that’s fun to play while still satisfyingly rewarding players for taking a break. Try it!


This combination of resource gathering and mathematical puzzle is very fresh and new. And addictive! Can’t stop playing. And no connection need, as well as no donation. Perfect.


We really like this game, but after we went through enough mana to activate the cult, it started randomly resetting on us every few minutes. (in other words, acting as though we had activated the cult again, even though we hadnt yet earned the mana id need to do so.) this totally broke the game. We deleted the app and started over, but the same thing happened once we activated the cult again. For now Im done trying, but we hope they fix it soon, because id love to give this app the rating it deserves.


Nice start, could use some polish.
