It's not that hard to make a good tower defense game. But as far as I can tell these are the first guys to do one right for mobile. Encompassing all elements of types of grades and mazing, difficulty scales beautifully and there's a freemium option for noobs. Well rounded and recommended

Edit: ok, got it. I should be clearer, the "relic" tiles look a look like the normal unbreakable ones. Cannot collect relics. The encyclopedia doesn't help to know HOW to collect them. I assumed you had to build a turret on top of relic parts, but this never got me any.

Fun until it gets gimmicky. Too many TD games suffer from that problem. Sad to see this is one. Invisible enemies, immunity to traps, enemies that destroy your towers...there are ways to make a game difficult without cheap gimmicks. And the ooze enemies are totally overpowered. Forced to use diamonds on almost every level in Chapter 4. When I ran out, I uninstalled. I'm not going to pay to win.

Great game! It's difficult to find those nowadays. However, after the first 2 worlds/pages it gets pretty stagnant. I wish there were more upgrades. I'm bored. :(

This is a brilliant little tower defence game. Teaches you at a good pace and doesn't overwhelme yet is complicated enough to keep your interest throughout each new level. Only gripe is the flashing ads at the bottom, it wouldn't be so bad if they were static but the flashing is very distracting.

This is a pretty fun game with some originally, which is hard to do in this genre. The gameplay is fairly unique too, with some nice little touches such as being able to link turrets to boost their abilities. If I had one grumble, it's that the ads at the bottom of the screen cause the game to stutter on my Nexus 6P, so I'd prefer it if they were less intrusive.

Used to love this game. The new ad strip in-game has totally ruined gameplay and frame rate. Leas than 5 fps now. Way to ruin a good game just so you can line your pockets a bit more!

Best TD-game I've played so far. Would have liked to be able prioritise enemies to target (ie strongest, closest ect) and that earth has a tiny chance of stun without upgrades. Some enemies could also have looked more beautiful.

Best tower defence game I've played. Devs: An undo button would be nice (for single silly placement mistakes), and how about a level editor? Editor could be free to use, but pay a small fee to enable level sharing.

Very good take on TD genre. Just some levels feel a bit unbalanced, requiring you to play very specific strategies to get a decent rating (or using cash).

Good td game and shows details for what an upgrade cost and what it does. It gets harder and you have to continuously change strategies for each page of challenges. I would recommend.

Great TD game. Love having some control over pathing. Pay to win is not in your face; I have spent a single premium currency and u get tons of it just for playing the game - it's just well-balanced as is.

It's not pay to win, it has fresh game mechanics, multiple upgrade systems and you can undo upgrades if you want. This game is an 11/10

Hello, I love the game, just wanted to let you know : on Galaxy S8, the bottom of the screen keeps the image from the previous scene. It doesn't alter the gameplay of course but it doesn't look good :p Edit : fixed, thanks a lot!

Best mobile phone game I've played. Challenging in the best way: makes you think hard and come up with new strategies to get past the levels that you can't master at first. It's great how sometimes you can just barely pass a level, but then come back to the same level and improve your performance to earn upgrades that may be just enough to help you beat other levels that you could not pass before. Also the ability to endlessly, freely reconfigure your upgrades any time (rebuild skill trees to highlight different strengths, but always keeping the same number of skill points you've earned so far) adds another dimension of strategy that keeps level after level of "only" different enemies and layout from getting old too quickly. I have played other far more complex games than this, such as all the city/empire builder/army games, and honestly I have more fun with just simple tower defense. I know I'll run out of levels and get over it, but even so, this is the best example of its type. Very well made.

Eu estava na onda 8/10 do nível 14, ai eu dei pause e sai do jogo, ao retornar a fase tinha sumido e tive que fazer tudo de novo! Que tipo de pause é esse?😠 Corrijam isso serio!

Same as the last ones but still good. More difficult than I remembered

DigDug with tower defense, this game is highly entertaining and well crafted. With flexible upgrades for the towers (can be refunded for the stars and relics used to enhance them), the developers have made an excellent program that stands out from the crowd.

A unique tower defence game. Super enjoyable and addicting. I haven't experienced any glitches or issues.

Just started, very interesting mechanics. I like it. Edit: after almost a year I have finally finished it. I loved the experience this game is giving, enjoyed sweet relax while playing. Definitely 10/10 mobile game.

This is what I like in a mobile game. Easy to play, good controls, and you don't have to pay to win. Yes the game would be more of a grind if you free play it, but it is quite doable. Nice game

I wanted to waste 5ime while stuck on location. This did just that.

If it weren't for the constant ad banner at the bottom this game would be good.

No kidding that ad strip makes FPS stupidly laggy. Uninstalled 10 seconds after launching.

This is a creative, and well made game that was made with a lot of effort as it is very clever in how it works. The overall vameplay is smooth and it is a very good time killer that is easy to pick up.

Enjoyable to play with as much focus as you wish to give the game. You can try to squeeze out max rewards, or just get the level over with.

Can't think of a single criticism. Awesome TD game. Not ruined by wait mechanics or pay to play. Quality buffs if you do want to invest though. Great game.

A really fun tower defence game, graphics are not ground breaking, but they are nice to look at, gameplay is simple and fun.

Fun, but it sometimes restarts when I've switched to another app mid-level and I lose my progress.

I finished this game just now. I got all 3 stars all the achievements all the relics. thanks for the great game! time to un-install :(

Good game, I like the idea and gameplay. Simple and easy to understand but gets more stragtic as you move through it

Extremely annoying ads. Boring game play.

Great tower defense game. The mechanics are fun and interesting, and the freemium model does not hinder it at all.

Just complicated enough to prompt some planning, a good way to pass time.

Great game overall. Wish you could earn more diamonds at a time but overall my favorite to play

One of the best tower defense games, difficulty builds nicely!! Very tough!!

Great basic tower defense game. Easy to get into. Only takes a few minutes to play a level

Bit boring, but not too bad.

A well executed tower defense game with interesting strategic options, good tutorials, and clear interface.

Pretty good but later levels lag causing the level to be unplayable.
