This was really fun. I managed to get to level 30, and I'm not sure if it was just me or not but the game seemed to slow down a lot in the 20s with loading the level requirements, and it didn't load one for level 30 at all so I wasn't able to progress. Maybe 30 is the last level?
In any case, it was great to see how many shapes I could make, even exceeding the level requirements sometimes. Being able to redraw smaller shapes over big ones to make a more interesting design was a major appeal to me, too. I love that this game combines artistry and puzzle-solving.
