fun game, great concept! =) i loved map 9, 11, & similar- having to interact with moving structures or draw while moving seemed to really bring out the strength of this concept =D i noticed that: 1) jump sound seems to trigger when walking over irregular shallow slopes or when falling down against steep slopes- that can get a bit annoying; 2) if character is falling too fast (from top to bottom of screen) he will pass through drawn lines. yay
