Good god, at last.

Used Flixel for this, my first time with it. Love it, though it took me quite a while to make it do what I wanted (specifically the running on walls and ceilings bit).

The tiny pixel font was made during the competition, and it's available here: http://fontstruct.fontshop.com/fontstructions/show/plink_1

Would've liked to make at least a simple looping background track for the game, but I had no time left for such things. Improving the level design would have been a priority anyway.
