This was pretty cool! I like the concept and the minimalistic art style - it really fits the game. Perhaps there could be a score target to beat for each puzzle so that you don't end with the slim rectangles everywhere?
Thanks for playing, and for the kind words! Good idea—I'm thinking for the future to maybe make it 1 star = any solution, 2 stars = decent area-enclosing solution, and 3 stars = optimal solution. With some larger & better designed levels.
