### 3/5 — А

*2026-08-21*

Заипала эта реклама Лига ставок, зависает без остановки крутит свою беспонтовую каличную рулетку 🤬

### 3/5 — В игру не заходит

*2026-08-19*

После обновления не могу зайти в игру, телефон айфон 16 pro max

### 2/5 — 게임은 너무 재밌는 구성인데 번역이 가장 큰 문제

*2026-08-17*

여기저기서 주는 보상들을 어디에 써야하는지도 잘 모르겠고.. 그 보상들로 스펙업시키고 하는 구조 같은데 게임 좋아하고 자주하는 저도 좀 이해가 어렵네요

### 4/5 — Game

*2026-08-17*

Great game. A little too much ads. Feel like a chore every day

### 5/5 — Boom

*2026-08-15, version 1.9.7*

Absolutely love this game…..

### 1/5 — It’s fun for a week.

*2026-08-14*

It’s really unbalanced game. Some the troops are so hard to put down. Halfway through act 2 becomes impossible to 3 star. To many things require gold, not enough gold given out. Arena is stupid hard.

Update: no improvements, it’s very clear to me developers are using this game as a cash grab. They comment that the other activities are how to progress but getting past the 3rd stage is stupid hard. The leveling progression is slow. The bosses are OP, Cobalt Reaper for instance says it takes +50% fire dmg, that’s a lie, they must have forgot to actually add it in. Never won a round of arena. Gear/hero leveling is absurd, thousands of gold for single level while getting 180 at a time without watching some add. The pace of the game in every aspect ruins it.

**Developer response:** Thank you for your feedback! We understand that Act 2, Arena difficulty, and gold progression can feel unbalanced. Main stages are meant to be challenging, while other modes and previous stages help you gather resources for upgrades. We’re continuing to review difficulty and the economy. We hope you’ll try the next update!

### 1/5 — Удаляй быстрее - экономь время!

*2026-08-14*

Долго конечно я играл, не хотел удалять, но терпение лопнуло!
Игра построена чисто «лутке». Смотри рекламу - будет тебе счастье!
Сегодня потратив 1500 жизней, прошел - 0 уровней, 0 уровней, Карл!
В игре меняется только сложность и то только вверх. Играть можно только за 2-3 персов, остальные зачем?
Нельзя сделать выбор хотя бы одно перса в начале битвы, чтобы хоть  чуть увеличить шансы?Из 10 битв только 1 выдает нормальных персов, но сложность… даже не хочется повторяться!
Вообщем и целом - дно!
В утиль!
Разработчики молодцы!

### 5/5 — Игра

*2026-08-11, version 1.9.6*

Огонь игра

*2026-08-10*

VIP 광고패스 평생 이용권 비활성화 되어 며칠동안 제대로 게임도 못하고 있음. 이런 말도 안되는 버그 만들어 놓고 메일 대응도 안하네.
