It was really fun except if you hit the cube on the edge of something it would rotate and what you were using to detect the ground doesn't work while rotated otherwise it was a very fun game :D

Sweet and Simple with an awesome main menu

Nice game! Few things I want to mention. Why didn't you use the music from main menu in game? I think it could have done good for the game. I found it bit frustrating in some levels where you didn't see ahead. It has potential, maybe adding some enemies or more different mechanics or just sound effects would be great. The white background in spikes is easily fixable, I can help you with that if you want. Overall nice job!
