Crayon Physics Deluxe creator Petri Purho is celebrating a birthday. His present to us is that he is implementing a pay what you want for his award winning title, Crayon Physics Deluxe! Crayon Physics Deluxe is a very simple and fun game, wherein you "control" a ball that needs to collect stars. But collecting stars isn't always easy, so you can draw in ramps, blocks, and stuff of that nature to help you out.
