Really cool in pretty much every aspect. I enjoyed the camera zoom (though I imagine that it could be improved with more time). The limited amount of paint made me to use very small lines in an effective way instead of wasting it. I can easily see this as a full game, maybe with obstacles that force you to use the lines in different ways.
It only happened once, but when I ran out of paint the chicken fell very slowly, so it took a long time to end. Apart from that, it runs perfectly!
