Used to be GoodSorry to say but forced adds is NOT cool. Getting worse recently. Sad to leave but it is not enjoyable playing it anymore.

Constant ad interruptionsThis game used to be fine. Now, they constantly interrupt play with a forced ad!! I MEAN every few minutes, if not every minute!! You then have to click out of it and wait for the game to load again!! I’m finding a new one. This one sucks!!

Intrusive AdsBefore you get stuck in a loop of “ads” which are just other games, it’s quite fun. But once they send you down that ad loop, there’s no escape. You play a different game and there’s no exit button. You close the app, and it just sends you back.

Used to be GoodUPDATE 8/26/26 Have been playing again since yesterday, and no more forced adds so far. Well done! Sorry to say but forced adds is NOT cool. Getting worse recently. Sad to leave but it is not enjoyable playing it anymore.

Отлично, но…Приложение отличное! Уже несколько дет играю только в нем. Но после обновления в ежедневных заданиях появляется только легкий уровень сложности! Раньше у меня был уровень Киллер. Сейчас не интересно. Сделайте возможность выбора себе уровня в ежедневном задании или хотя бы из последнего выполненного!

БатлКогда в батле доходишь до 100 уровня, хорошо бы чтобы он снижался при проигрыше, все интереснее будет, а то и так короткий проход от 50, так и интерес пропадает. А вообще отличная игра
