### 3/5 — Хммм

*2023-08-30*

Разработчики, я конечно очень рад что выходит обнова через 5 минут после моего отзыва, что все хорошо кроме малого количества уровней. Новые механики в игре и система сбора все круто. НО, вы не хотите вернуть прогресс до обновы людям? Мне вот лень снова уровень персонажа качать и открывать все оружие, как то не правильно это, а так, обнова хорошая

### 5/5 — Good games hope to be updated.
