This starts out easy, but every time you successfully complete one of the all-white puzzles, you get another one with more pieces. I can't seem to stop playing... I want to know how large the final puzzle gets! If anyone gets there, let me know.

Is there any way to save your game so you don't have to replay when you go back?
