I achieved level 11… that's very hard (even though sometimes it's almost trivial). Could you display the sprite-goal in a corner of the screen? It would be incredibly useful :)

The behavior of up and down arrows are bit weird. I mean: the left and right arrows always make the same rotation (from the point of view of the player), but the effect of the up and down arrows depend on the object rotation, so it's difficult to control.

Very cool, but insanely hard for me!  I still haven't beat level 00. lol

Could you upload an HTML version to make it easier to play? :)
