It’s not as suspected, but it’s OK

Бесконечная реклама

Прошёл волну, смотри рекламу, не рекомендую к скачиванию!

Response from developer

Полностью понимаем, как раздражает реклама, и спасибо, что написали. Попробуйте режим ENDLESS: во время игры там нет рекламы, так что можно играть сколько угодно без перерывов, разве что вы сами захотите посмотреть рекламу за награду. Надеемся, вы дадите игре ещё один шанс! Totally understand the frustration with ads, and thank you for telling us. If you'd like a break from them, try ENDLESS mode: there are no ads during gameplay, so you can play as long as you like with no interruptions, unless you choose to watch one for a reward. Hope you'll give it another try!

Great time sink

I really just play the unlimited mode, so can’t comment on the level progression, but I absolutely love this game. It seems extremely well balanced where it’s difficult, but doable, and it seems to scale fine. When I’ve lost, it was close and purely through poor choices I made, not some unbeatable obstacle. Math and strategy, what’s not to love?
