### 3/5 — Fun, but broken on iPad

*2026-07-24*

So this has so much promise but none of the abilities will work for me on the iPad. It’s kind of hard to advance without them, so I’m kind of stuck. I wish I hadn’t purchased the paid version because there’s no benefit for me. Such a bummer.

### 5/5 — Idea

*2026-05-21*

I have an idea where you can get a Gate and a Button (Both in one if it works) and the Button closes and opens the Gate. After the Round the Gates close.it would be cool Becuse you can make a Long thing with a Sniper and the enemys Must Spiral alot to get there.also  this game is very cool

### 3/5 — タワー売らせて

*2024-04-04, version 2.3.2*

タワー取ったらワンゲーム中は二度と売れないから注意。
セオリー通りに敵を遠回りさせつつ、遠距離とヒールさえ取れば楽々クリア可能。

真新しさは全く無いけど、ゲームとして遊べるから評価は中央の星3。

ちなみに難易度ノーマル以降は課金らしいので、これ以上遊ぶつもりはないです。どうもありがとうございました。

### 3/5 — Paying for different experiences

*2024-02-29*

The f2p experience turns it into a rougelike, but if you pay it’s a rougelite basically

### 5/5 — Thanks!

*2023-11-22*

Simple strategy game that I can’t seem to get bored of!

### 5/5 — Great game where the key is the maze building

*2023-05-10, version 2.3.2*

Great tower maze oriented game. Few in its genre

### 3/5 — うーん

*2023-04-29, version 2.3.2*

1ウェーブ終了ごとに、報酬を選ぶという仕組み。報酬はタワーだったり、タワーの性能アップだったり。あるタワーをあえて選ばなかったら、その後ずっとそのタワーは報酬として出てこなくなり、永遠に使えない感じだった。

### 5/5 — Best Tower Defense game out there!

*2022-11-28*

Full stop, nothing more to say…

### 5/5 — Enjoyable

*2022-08-20*

The game has a nice logic. Simple but exciting. I recommend everyone to give it a try.

### 1/5 — Por lo probado en iPad Air 2 no funciona

*2022-08-11, version 2.3.2*

El juego no funciona en un iPad Air 2

## Version history (last 5 of 5)

### 2.3.2 — 2022-01-13

- Fixed caching for purchases for offline play
- The restart button is now disabled for daily challenge games
- Restarting a game will now keep the selected supercharge
- The score bonus for unused mastery points is now tied to the amount of waves played so creating and immediately abandoning games can no longer be exploited to gain infinite XP
- You can no longer abandon an already abandoned game for infinite XP

### 2.3.1 — 2021-11-01

Fixed an error in the score calculation bonus introduced with the last patch.

### 2.3.0 — 2021-10-11

Added

- new supercharge *Tanky*, in which mobs have more health but move more slowly
- new supercharge *BadaBoom*, in which only Powder Kegs are spawned

Changed

- All run scores now have a bonus for every mastery point NOT used to level the playing field in the daily challenge
- Supercharges in normal games are no longer random and can manually be selected
- Updated several translations

Fixed

- Fixed an issue where a corrupted profile would prevent you from starting games
- In case of a late (invalid) submission to the daily challenge you're no longer locked out of the next one
- The compendium now shows the proper amount of unlocked mastery points
- The level up notification no longer shows once you reached the maximum level

### 2.2.0 — 2021-07-02

Over the past couple of months I've been fiddling with the mobile ads and have finally decided to remove them; I wanted for you to be able to use rewarded ads to get a little help here and there but ultimately, they didn't do that job properly. 

That's why I've decided to remove all ads from the game and replace them with a consumable ingame currency that you can buy. As premium user, you can disable this just like you could disable the ads, but if you like these little bonuses here and there, you can now use them consistently.

Changed

- Reworked the mastery selection when starting a new game: now has previous and next buttons to work around the buggy iOS select dialog

Fixed

- You can now scroll to reach the highscore graphic's download button on small screens

### 2.1.2 — 2021-06-25

Added
- Added simple export / import for profiles
- Even though the mobile version has thousands of players, the game has only a handful of reviews so I had to add a rating prompt ;-)

Changed
- Endless rewards now always appear in the same order
- The keyboard shortcut to cycle the game speed can now also be used to reroll rewards

Fixed
- Removed deprecated range stat from ability details
- Fixed color picker bug which would sometimes lead to a missing primary color
- Fixed the infinite mastery point exploit
- You can no longer submit scores to the daily challenge abusing the infinite mastery point exploit
