I loved it tbh,
The turtle race was challenging,
one wish I have, is for the white bar to move when you fail to time it also.
I liked the twist of the math problems, it felt good, might be hard for math challenged people tho.
The boss fight was amazing, I really wish there were sounds and music to it, would have made it epic.
If I have to critique something: the game screen goes out of frame a little when the screen started spinning.
Good job :D
