I really liked the game, but I ran into some issues on Android:
The amount of points per second I got didn't seem to increase somewhere between 100-120 thousand per second, no matter how much I upgraded other characters. This wasn't fixed by closing and opening the app or even reinstalling.
While watching an animation, it seemed to loop between two frames and after trying to watch the animation again a few times it didn't get fix and the app actually crashed which made me lose all my progress.
