I just play your's , it's cool , the mechanics are solid and I like being 2 player and it's easy to switch  between them, but you could do better with the graphics, I have the same problem that Sylv'Alion mention , but over all the game is good also I like how the bg-color change depending on the current player color...

I hope you play my game, and take care of your hand it's important for a game dev
