Interesting concept. The levels become progressively more difficult, but not too difficult so as to be discouraging to the player. The game has achieved a nice balance between playability and challenge.
I like the little extra of the title screen's instructions falling into bits and individual letters. Nice effect!
The gamejam's "unstable" theme was very well implemented in this game, to make an understatement. It was incorporated as an integral component of the game, not just tacked on lightly. Nice job!
