Very, very "early alpha" playable version here: ragtag.magmafortress.com
I fixed up all the major bugs (that I know of,) added some more abilities then set it up so that you respawn with a randomised set of abilities whenever you die.
Then I wasted a lot of time trying to figure out why the game was not running the same on Google App Engine as it does on my desktop. I wish I'd tested this more before the challenge.
It basically came down to differences in the way some openGL resources are initialised.
Anyway, I'm happy to have a version released already.
