Игра хорошая!

Но очень много рекламы, и есть вопрос, почему в событие Balloon Rise не проходит дальше 28 этапа, а из 35, что делать?

Ridiculous Ads

I couldn't get past level 32 due to the amount of ads. Just this one level continuously glitched out due to the ads. I could only play the easy part and when it switched to the "hard" part of the level the ads did not stop. I watched 4 ads and it still would not let me actually play the level.
