Really nice feel for being an eraser... nice work with the smudges, the simple way you teach how to erase to unlock the PLAY button. Nice little game, well polished within just the weeks worth of time we were given. Only thing that got me by surprise was that it wasn't obvious to me until too late that I was using up my eraser with every erase (I mean, obvious in hindsight) but if that was made more apparent somehow early on, that might be neat.
