Very cute game. Mechanics reminded me of "Max & The Magic Marker" (took me a bit of time to remember the name). Except yours is much tougher due to physics - I wouldn't have been able to solve the majority on my own. Or it would've taken me a long time. I reached the "cans of paint balancing on the ruler" level.
Graphics are simple yet cute, love the fact that paint is left on the stage after every single action. I very much dig the mechanics, and addition of different properties for the drawn lines is a nice touch.
I didn't expect this to be a puzzle game, but I liked it quite a lot. Good stuff!
