Great game

Love it

Faster leveling

I love this game. But the devs make leveling up faster

Ok game

Great little time waster. Fun mindless game.

Absolutely horrible

This is the worst game of this genre - no disrespect intended but this game is slow and just bad

Типичная донатная помойка

Тонны улучшений за реал/донатную валюту. Полного заряда энергии сейчас хватает всего на 4 боя. Улучшение героев стоит нереально дорого,за бой выдают копейки. Очень жаль,хотелось играть(((

Response from developer

Спасибо за ваш отзыв! Понимаем, что стоимость улучшений, ограничение энергии и количество наград могут сильно замедлять прогресс. Текущая экономика рассчитана на долгосрочную игру, но мы продолжаем пересматривать награды, цены улучшений и темп прогрессии. Надеемся, вы попробуете следующий update!
