### 1/5 — Классика, что раньше было лучше))

*2025-11-09, version 3.0.13*

Раньше рекламу можно было скорее самому посмотреть по желанию для получения плюшек нежели она сама запускалась. Сейчас же на любой чих - запускается реклама. 5 минут ностальгии и удаляю, эта ситуация с количеством рекламы - отвратительна по отношению к пользователю

### 1/5 — Вылетает

*2025-06-23, version 3.0.13*

Тупо вылетает . iPhone 14 , 18.5 iOS . Не грузится и вылетает. Купил 3й ранг. Верните деньги!

### 1/5 — Оплатил и приложение перестало работать)))

*2025-04-03, version 3.0.13*

Как только оплатил подписку без рекламы, игра перестала работать, фантастика)) просто во время загрузки приложение вылетает и всё. Это фитча или баг?) жесть)

### 5/5 — Great game

*2021-09-07*

Once I figured out how and what to do I have really enjoyed this game. It was really confusing at first and I almost quit. A little more help along the way, and the things telling me that I had enough resources to do something staying long enough for me to read would be very helpful.
