### 1/5 — $50 for that package is insane

*2026-07-29*

Get a grip 😂😂

### 4/5 — Fun, but slow progress

*2026-07-29*

I have played many tower defense games. I do recommend this one. This one is a bit unique and has some fun attributes that are simple, but add a fun layer to the game. I have been playing for several weeks causally as I can (no money spent, but watched many adds as I wanted to help with progress).  The mini games are fun and add a nice layer to the game.

The issue I have is the progress is slow for World 2. I have been on it for about a week and progressed all the way to wave 50, but continue to get one shot by the boss no matter my health/regen/shield/etc. I would be good with some challenge, but this is a massive one shot (over 68,000 hp + 10,000 shield.

I have not unlocked all of the tower levels yet (I almost to level 4). I am hoping it unlocks something to help with the bosses. I have also maxed out most of the attack attributes.

### 2/5 — Worst

*2026-07-15, version 5.0.2*

I’ve already bought an premium pass but , it disappears every time when I close and reopen the app

### 4/5 — good

*2026-07-12, version 5.0.2*

hi! This game is awesome but I think you devs should add stun ability (or what u call it) anyways keep going!
:)

### 1/5 — Needs delay time on displaying ads after death

*2026-07-04, version 5.0.2*

I have accidentally pressed to watch ads a couple of times now because it “conveniently” pops up at where I’m clicking at. Either it has to move or ad a delay for popups after death

### 1/5 — Trash

*2026-07-01, version 5.0.2*

App frequently, 90% of the time, won’t finish loading past 65% so it’s unplayable.

### 1/5 — Ad

*2026-06-29, version 5.0.2*

Why can't I watch the ad? I used to be able to watch it, but now I can't.

### 1/5 — Constant rollback for no reason

*2026-06-28, version 5.0.2*

It will rollback once you logout or exit from game. Removing your whole day effort.

### 3/5 — Реклама

*2026-06-25*

Не могу посмотреть рекламу . Из-за этого теряю много плюх в игре . Айфон , Россия

### 1/5 — 為什麼我訂閱490訂閱

*2026-06-17, version 5.0.2*

為什麼我訂閱490的卻沒有給我490的內容？吃我錢嗎？
