Community Insight:
We used to play game on the windows phone and was delighted to see it on the iPhone. Hours of fun.
We played this years ago on iPhone 3, we thinkso glad to have found it again! Gaming Zen for us. Simple, colorful, satisfying.
Thanks for bringing this game back! Shoulda zagged seems impossible now though.
The most underrated tower defense game on the app store. Truly one of the best. Art.
Ive been playing this game for over 10 years now. Many thanks to the developers for keeping it current. It is one of the best OG tower games. LOVE IT.
The Best, our favorite, hands down.
This game was one of our favorite original iPhone games. A fun and challenging game, that works offline. Our brother and we would compete to see who could complete the level first. Love the remake. We will definitely buy more levels if there are any new releases.
Great game. We just wish the second one and the correct hexagon defense games were restored as well.
GeoDefense was one of our favorite games in the early days of iOS, and Ive searched for years for another tower defense game that matched it. This remake is spot on for the original, and if you liked that, youll like this. Its a simple game, easy to grasp but with enough challenge to make you think. No in app purchases, a real throwback.
We adored this game 15 years ago. So perfect. It felt magical. And it still feels magical! However, overall most levels are 75% less challenging than they used to be. We just played one of the final Hard levels and no critters lasted longer than a half second because the towers destroyed them immediately. We hope the developers take notice. The original game was challenging. It may have been a little too hard! But as it is now, its so easy its not a challenge, and not fun to play. Maybe Im just a genius now, older, wiser. But we doubt it, its just very, very easy. You can do it, devs! Make it more challenging.
If you added endless mode, we wouldnt have to replay levels. Just our opinion, still a good game.
Love the game, but Not enough extra levels for 5$.
We absolutely love this game and am so excited it's back on the App Store! We originally played GeoDefense many years ago and it has remained one of our all-time favorite tower defense games. The developers did an amazing job revamping it for iOS – the graphics and gameplay are just as great as we remember. Installing this game immediately brought back waves of nostalgia. The vector graphics are simple yet striking, and truly capture the old-school vibe. The towers offer a great variety of strategic options to counter enemies. With 30 increasingly challenging levels, this game keeps us coming back again and again to try and beat our high score. Kudos to the developers for reviving this classic so skillfully. Five stars for sure – we would absolutely recommend GeoDefense to any fan of tower defense games looking for a blast from the past.
Glad to finally have found this remake of our all time favorite Tower Defense game. Great job.
Thought it was gone when iOS went 64bit. Just found this updated version. A great time killer.
Loved this game back in the day! This is pretty faithful to Critical Thoughts original version. The Geo Defense series are to this day our favorite TD games, with Geo Swarm our #1. Any chance of Swarm getting revived.
We were never so happy to see GeoDefense is back! A new developer has resurrected it to play on modern versions of iOS. If you liked the original, or just looking for a great game, check this one out. The Easy levels are free to play, and for $3.99 you can purchase the Medium and Hard levels. We purchased them right a way to support (and to say Thank You, to the developer).
This has been one of our favorite TD games of all time. Its challenging, but not unbeatable. Im glad this has been restored as Ive been missing this game.
This is really fun and we really recommend it. The 5$ is WORTH it.
Thank you from bringing this back. Please bring back Swarm. Edit; Im stuck on level 6 beginner and we dont remember it being this hard. The normal strategy used doesnt apply to this level remake. Its not a one for one transition to the new game engine, the level design to subtlety different.
We were falling asleep last night and this old game randomly came through our head – we used to play it 10 years ago (!!) and it was our favorite. So we took our phone off the charger and searched to see if it was still in the App Store. The old one has been removed, but we didnt expect it to work anymore anyways. But we were SO thrilled to see that not only is the game re-created – its rebuilt and currently being maintained! Lots of nostalgia here, as this was actually a well-built strategy game that you can just pickup and play and has much challenge to it. Thank you for bringing it back.
Wish there would be more maps or map editor for this game. Also love to see GeoDefense Swam released.
The game is beautiful and almost flawless as a TD game. The only thing that kept it from 5 s is there are only 30 levels. If the developer is only going to have such a limited number of levels, include a level builder.
Than vector. Fonts on menus especially true. Actual graphics OK.
We like this one more than color defense but color defense requires you to be a little more crafty about how you place your towers. This one kinda seems like the obvious way is gonna work most of the time.
Game seems really good, but 2 hard levels need to be tweaked. The Eye can be beat with 1 lvl 1 laser, and Resistance is Futile can be finished with 1 lvl 7 laser. We wish you would add a switch to make it run until you lost all lives, instead of just finishing the levels. More levels would be nice too. Ive played these over and over, trying to find the best setup.
We're glad that this still exists in some form. It has been one of our favorite tower defense games going back 15 years. That said, all the levels can be beaten within several hours, and the replayability is minimal. We would really like to see more levels. If the dev could allow users to create and share new levels, or submit new levels that could be added under a custom game difficulty, it would be incredible! Dev: please please add this.
Some of levels are stupidly easy. Like the only way you could fail some of these levels is to fall asleep. (Resistance is Futile being the worst). In the old game you could link the level 7 shock towers which was the coolest thing you could do. But not now. Still its fun to play.
But we have to agree with several of the reviews here. The balancing is off a tad. The easy levels are harder and the hard levels are easy. Something isnt quite tuned right. That said, still a wonderful game and a very close approximation.
Great game we have enjoyed it for a while. We just purchased a new we pad and we click the restore purchase tab and nothing. We know it is only 4.99 but we have already paid it.
Most of it works but several bugs make it a bit disappointing. Most annoying is that in some levels the difficulty and or increase in attacking waves does not happen. In one particular level with 40 waves you see the exact same 4 creeps over and over for the last several waves, making it easy to beat, and boring. This was not how the original was.
This game is awesome! But it has not been updated since 2 years, we would love to have new worlds and levels/towers.
- (Balance) Level difficulty balance 2. (History) A local history, best score per level, fastest time, fewest/most towers per level; most money spent/not spent; its surprising there isnt one. 3. (Levels) More levels, or a level editor/tweaker. 4. (Stopwatch) How fast did it take us to get through all the levels in a single set. 5. (Swarm) :D Swarm Meme le System-D peut montrer des amliorations :).
We were so excited to repurchase this when we saw its back! In many ways it is the same game, but in one crucial aspect it isnt: The difficulty. The hard levels used to genuinely be hard. We tried many different strategies and failed over and over again to beat them. Now theyre all just easy. Feels like we dont need strategy at all. 10+ years ago we spent hours trying to strategize through this. Now we just burned through the whole game with little challenge. And no, its not because we got smarter lol. We also noticed there used to be creeps that were immune to various kinds of weapons (which would force you to think out of the box and adapt to new strategies) which have been removed from the game, further simplifying it. The nostalgia is great. The game WAS fantastic. But the rework is not faithful enough to recommend again.
Don't get us wrong, we absolutely love this game. But 30 levels is not nearly enough, especially when other tower defense games literally have thousands of levels. The developers need to supply an update or do a GeoDefense 2.0 that's more in line with current TD games.
Nice game and worth the small fee, but way too easy. The level rating is messed up as most hard levels are actually pretty easy, including the final one. You will quickly blast thru the levels and have fun doing it, but that's it. Needs more levels and more thought given to difficulty.
The original was tough and our all time favorite tower defense game. This new version is just too easy, especially the hard levels.
We ended up paying so we could have all the levels. But we needed up going through every single level in a week. Theres only 30 levels total. Personally, it would have been worth only .99 to pay instead of the original price. For over $4, we would hope to get at least 100-150 levels. It is a fun game and has good challenges. It just ended really quickly.
The game is clean, clever in its descriptions, and has a nice unique graphics ambience. However, its just way too simple. There are only 5 types of towers, and on most levels either blue or red tower spam will make it absurdly easy. We just played all the way through and just didnt feel challenged on any level. We dont consider ourselves to be particularly good at TD games, we think GeoDefense is just too easy. Even the hard maps are almost mindlessly easy. It would be very simple to create a hard mode where creeps had 1.5x health, or moved slightly faster, or where your max lives were reduced to 1. Not a bad game, 3 stars for sure, but not the best investment of time or money.
Something is just off on this remake. The fonts dont quite render correctly, and the animations for some of the creeps looks off like its being stretched or something.
Not sure why, but the developers changed this version of the game. The hard levels are now easy; we remember in the original having to work a little to win "The Eye", but in this version it's trivial. Meanwhile we're fairly certain that the easy level "Shoulda Zagged" is now impossible. Generally it seems like they've messed with the parameters for each of the levels, and the result is a less well balanced game.
We LOVED the old version of this game, and am glad to see it back. However, whereas the original version was perfectly balanced and extremely challenging, with each level requiring a lot of experimentation to find the right combination and timing to master, this version appears to have no tuning whatsoever. A few early levels have some challenges, but most (especially the hard levels) are stupid easy. Just pile up a handful of anything and you will win, dont even have to add anything for the latter waves. The challenge and strategy is non existent. This remake nails the look and feel of the original, but fails the gameplay and tuning.
Easy level 6 – Shoulda zagged is broken. We have yet to find a viable way to complete this one. There are medium levels that are far easier. It seems to start slow, which prevents you from getting upgrades. Then the creeps start pouring in on the third wave. Online walkthroughs seem to show a smaller level where the blaster is able to cover more area, but thats not how our version of the level looks.
We had this on our 3GS back in the day. This version isnt as sharp, responsive or playable. Controls are sluggish and infuriating. Glade we didnt pay for it.
Loved the original game. As other reviewers have noted, this remastered version gets the look and feel just right. But the levels are not balanced and everything after the easy levels is notably easier than it should be. Would love to see an update that adds back the difficulty and problem-solving strategies that the original game demanded. Plus maybe some additional levels.
Years ago this used to be our favorite IOS game (along with GeoDefense Swarm). Thank you for bringing it back!! Unfortunately, in this reboot the levels are way too hard. Im struggling to get through even the easy levels… We like a challenge, but these are just too hard to finish.
The physical scaling of the towers is not the same as the original. The blasters, etc., are graphically tinier so range is not as big. For example, on easy level six its nearly impossible to beat that level when you compare the YouTube walk-throughs of the original game, which is much easier.
A good tower defense game, some good levels. Bad UI – the level select screen doesnt tell you which ones you completed. The difficulty levels are wildly random. Some levels in Hard are laughably easy, while some levels in Easy are unpassably unfair. If you put a tower too far on the edge of the screen, it is unclickable. The final upgrade for the Missile tower makes it almost useless. We only upgrade it to level 6. The green tower is practically useless beyond the first level. Selling back your towers doesnt free up enough funds to be worth it. Its annoying we cannot toggle which enemy we want our towers to aim for. No music. No endless option.
This game was one of our favorites when it was first on the App Store. After downloading it again though, the app is very out of date. We cant redeem our old purchases and cant even attempt to buy the extra levels again. The game just crashes when we try. This really was one of the best apps on the App Store, but now its outdated and doesnt work with current software/ios updates.
Near non playable without paying it.
