I thought it was a pretty cool concept
I just wish you fleshed it out more. There's a lot that could be done with a puzzle game like this. Right now, for lack of better words, the game doesn't feel finished. When I complete a pie, there isn't really any signifier of if I did well, there isn't much of a curve to get people into the game (Bigger pie pieces, maybe rotating the pie pieces or maybe less colors at the start.) If you took one more week to just stuff some more content into the game, I think it could be something great.
