Ph, puzzles! I was thinking the feature to change a picture on the main menu was a bit of an odd commodity, haha, turns out that was the game. :D Would've been nice with a few more pictures to play around with, but it is working well. The gameplay is both easy to learn and challenging to complete, and the music pretty catchy, though it gets a bit monotone after a few loops. Would've been cool with one or two alternative tracks in different (less intense) styles. Keep it going!
