I think I cut the pie when it asked for two slices, but it allowed me to keep cutting until it went red. I appreciate the idea of the mouse action to slice it. I'm not sure if it was my own misunderstanding of the mechanic to do it properly.

the game stayed frozen after my first slice

Managed to beat on hard, though must admit that controls are somewhat confusing as slices are hit&miss when it comes to registering, especially when you try cutting triangle by traingle and not straight lines from one pizza edge to another. The music is boring repetitive, however the art direction and sound effects guided me a lot as a player to know if Im doing good or bad. Great UI as well, I'd change the font to something more readable next time though, at least in this resolution. Great job!
