Click on a square to change it's costume. Use the hints to reveal the hidden image. There were 3 puzzels when I shared this project, so there are currently 8 puzzles.
I'll add a level per love-it! 12-7-2016: Found out that there was a bug with drawing the hints. I will remake it anyway, the code is really messy. You should read the hints from bottom to top. And added a new level, 7x5 instead of 5x5.
