What a refreshing concept! I love it!
Honestly I was a tad confused with the tutorial and some of the interaction. Since the other crayons are outlined white I thought I could pick them up as well somehow and thought that was relevant to paint in a specific color (colors used in the preview of each level) and I was stumped that I couldn't click on the play and restart buttons until I understood the essence of the game. Could use a bit of polishing here and there with the tutorial, but other than that absolutely lovely.
