it's the same 10 levels on repeat. Im on level 50 and ive ran into only the same few levels. You cant get to x777. I'd give 0 stars if possible

★☆☆☆☆ stephanie evason · Aug 2, 2026

Highly inappropriate adverts for children, coming up at thr bottom of screen. Adverts after every level of the game.

★★☆☆☆ Dia · Oct 1, 2026

I kinda hate the game because the ads kept coming in the way, and I have to restart over on same level, like I just didn't do that now, t restart 3 times, and I'm tired of it.
