Community Insight:
We have a great time playing this game.
This is the best game no ads at all.
We love it. We love it. We love it. We love it it so much so much. Its our favorite game. We play it. 24 seven.
This is a great game! It is fun and addicting as well as the animation. All the sea creatures you get is super cute and wonderful. You can expand the aquarium which makes us feel a great deal as it feels like an accomplishment. All we want from this game more is more sea creatures. Everything else is great.
This game really pleases our love for the ocean plus no forced adds nothing but perfection.
Every other aquarium game on the App Store is cheap and uninteresting but this is fire. We fear this game cooked. The fish look so cute and Im happy. We can never say no to the seagull tho.
This is the best app for kids and adults! You can make your own aquarium.
We love fish and the graphics are they are good at designing the fish and we really like tycoons.
We LOVE THIS GAME! But think axolotls shold be added (unless there all ready in the game we have berly played this).
Such a fun and cute little game!! We love the graphics! So so frickin cute.
This is the greatest app ever made. No other game compares.
We downloaded this game during our afternoon layover to pass the time… Not even 12 hours later we have unlocked all of the rooms (maxed most of them out), filled all of our tanks, built an aquarium empire, completed all of the goals. We feel empty. We need more. We are so close to completely maxing out everything not even a full day in and we want to keep going. We beg for an update with new room additions! Or new fish.
This has been so fun they didnt lie about it on the add and its so interesting and entertaining we love this game we do recommend getting it.
This is the upgrade from private aquaria to exhibits that we wanted to see! There are a few small bugs that pop up every now and then, but theyre not regular occurrences. Theres finally some use for both currencies, its the perfect balance between easy playing and increasing costs of upgrades, and we can always use the extra time after beating the game to sell a few fish. Totally recommend even if you decide not to remove the ads.
The game is amazing but we think it would be better if you could have a deep sea area and a freshwater area because we feel kinda feel weird about putting the deep sea fish in the coral reef area and putting fresh water fish in saltwater tanks and also please add more fish.
This game keeps us on our feet we love it.
The game is great but need way more levels, more fish, bigger aquarium.
We love watching the fishes bob up and down. And all the animals r just adorable :3.
Its soooooo fun you can expand your aquarium and have thousands of people but you do have to upgrade you generation to have more fish tanks.
We completely all the tanks all upgrades in just 2 days but we were wondering will there be more added to the game? To us its just dead end XD.
It would be nice if you could merge fish that you have multiple of but best aquarium game Ive ever seen.
We like this game because people dont steal your fish to get money and we like simulators this one has chill music we love your game hope you can add more.
We love this game so much! Its so fun 100% would recommenmend.
Now we dont really write reviews a lot. And when we do its because we love the game. We love this game so so so so SO much! To the devs of your reading this, keep up the awesome work guys. 10/5.
We enjoyed playing this game, we really, truly did. Hence the 5 stars. The only in game issue we had was when the trawler set sail, came back, we collected our fish, and the game stuck on the dock. No biggie, we would just click a goal and it would pan us back over. That is, until we finished all of the goals and got stuck. The game was super duper easy to finish. We have all 30 fish, all our goals completed, every single area is maxed out in upgrades. Took about two-ish days with quite a few hours of breaks in between. Ive never had an idle game that we could, in a sense, beat? We just wish it had been longer, because now we have no idea what to do.
Honestly racking up 600k for the last few upgrades was tedious but its a pretty fun game regardless. Hoping for more updates in the future.
This game is quite literally perfect dont ever change it.
Its so much fun and if you like fish what are you waiting for come and play.
We like the lionfish and the fishes actually our awesome our favorite part is this is like a tycoon this is the best game ever read the title and the money you how many money you can get so cool you can have jam then add whats the electric four and how many visitors again so cool just get Braden eight10/10.
Ive been playing it for two hours we have not got bored.
We like ocean/water game and this game is best for us. We enjoy playing this! We think you should give this game a try.
No bot nonsense here. The game is good. We actually really enjoyed it. Really engaging. You progress FAST, and we mean FAST. The downside to that though You run out of content is a very short time. Ive played a total of around 3 hours and Ive completed all the goals and unlocked all areas. There is nothing else after this other than collecting money. Play the game and enjoy it, but dont spend money on it. You wont get your worth out of it. The game gets 4/5 for what we played though. If theres more coming, then Ill gladly come back. Great job so far, Devs.
This game is hands down our favorite game. It is so much fun, but you do have to watch a lot of ads to get things. :( (still our fav game!!).
We LOVE this game but we want rooms with dolphins, whales, sharks, orcas, etc.
This is such a good, addicting, game that we would want to play anytime. We just wish it would be harder, like the money seagull. We also wish that you could please add a breeding center, and the fish bringer should have like a 20 minute cooldown timer. This is really fun but could you please fix some of these.
You get the gist of the kawaii game in two mins. Worst amount and length of ads Ive ever seen but at least theyre varied and give you much in game cash.
We like the game, but sometimes there will be really inappropriate ads with nudity and other stuff like that.
We love this game but we completed it in one day.IT NEEDS A UPDATE.
We love the game but when we do the seagull videos it doesnt give us the money we won.
Took our money and didnt give us the item we purchased with actual money. It crashed as we paid for it.
Pretty great only annoying thing is all the ads kinda excessive but they are optional for the most part.
We purchased the small fish bundle it says purchased in the shop but we never received them and when we purchased it your game froze so we had to clear the app out we want what we purchased or a refund.
Ability to customize aquarium with colors/furniture Ability to rearrange exhibit locations More fish types/upgrading ship option.
The game is good for the first day of playing it, you can get pretty far into it just playing for thirty minutes and every so often throughout the day but it hardly ever does any background progress and logging back after a long period gives you hardly anything. Its a good time killer but thats about it. The missions end up getting locked behind you spinning a wheel which just makes you watch an ad. One of the missions is to watch 20 of these which is obnoxious and you cannot skip these missions. Ive also watched the ads and never received the reward which is worse. Game is just okay. Nothing special.
Game seems cute but there is an ad for almost every action. Just let us buy the game and play it ad free.
We love the game and everything about it. However when we do Gully Bonus and watch the ad theres a 50/50 chance that we actually get the reward even if we watched the entire ad.
Would like to be able to customize every tank.
We love the game but the bird that flys around is a scam makes you watch an add and you dont even get your money.
We downloaded this game on a whim, as we like to play idle games while work is quiet. This one seemed right up our alley; cute, low-poly design, fish and sea creatures galore, and silly puns. Its a cute game, and pleasant to play! However, its very, very basic. Now, we didnt expect it to be super detailed, but we were hoping for a bit more. You can only get four tanks to show off your fish, and you cant upgrade the amount of fish that can be displayed. You can put excess fish in the rock pool, but that just sells them. All other tanks are pre-designed with animals, which is fine, but it stops at penguins. Once youve completely upgraded everything to the penguins, the game is pretty much over. At first, we were considering spending the 10 dollars to get the ad-free version, but that was before we knew who lacking the game was. We hope it receives at update to add more tanks/animals/options, but Im not holding our breath. In short, its a fun and cute time killer, but needs major improvement if it wants to justify its ad-free price tag.
This game is, in concept, very fun. We like the visuals. We like upgrading our tanks and playing the game in general. Its well designed, and had potential to be great. But unfortunately, the game is way, WAY too short. Especially if you watch ads, you can burn through this game in less than a day, and once youve upgraded everything theres not much to do. Theres a very limited number of fish, and you can only use them for so many things. Id almost be able to excuse the ads, too, if they werent almost essential to progressing, and didnt cost an egregious $10 to remove. Updates and changes would make this a legitimately fun little game, but in its current state, we cant recommend it.
