The coolest puzzle game ever.

Ok, I finished it and am hoping he gets done with the final version soon, because a bunch of stages in this one depends on drawing what you want to happen and hoping the game will translate it to a salvageable object. I only beat the triple sea-saw stage when I got frustrated at the entire stage's perpetual motion and started drawing random lines all over the screen, at which my ball landed on a very thin rectangle that spanned the length of the level and allowed me to roll it to safety.

Great concept, though.

From my experimenting with it, it looks like the longer you draw a horribly mangled object, the more likely it'll interpret it. It's odd that it won't accept stairs, but crescents are perfectly fine.
