### 1/5 — Purchase

*2025-11-22, version 2.0.3*

I made a purchase, but it didn’t activate even though it deducted my money. Why?

### 2/5 — The hell

*2023-01-27, version 2.0.3*

I don’t trust you play tested this because all of the archers you can’t even see there body’s because they start shooting you before they are even on screen and you can’t actually kill them because your weapons can’t make it to them and this starts at level 5 you gona have to make them start shooting later then right away

### 2/5 — Игру забросили?

### 4/5 — I hate that we must wait a lot to continue playing other things are good

*2021-07-27, version 1.9.0*

Hi

### 3/5 — Glitch

*2021-04-07, version 1.8.5*

If you are reading this please beware of a glitch that could happen where a archer is off screen and you can’t hit it and no abilities can hit it either so I’ve experienced this glitch on level 5 and all I wanna say is that if you are thinking of playing this it’s a good game but it’s just a glitch which makes it impossible to move on.

### 5/5 — Awesome

*2021-03-21, version 1.8.5*

Awesome game

### 3/5 — Tạm

*2021-03-11, version 1.8.4*
