Rewrote and cleaned a large part of the code and added the basic framework for animated objects.
TODO: Nice input, introduce the World object, rewrite and optimize rendering, level generation (don't know if I'm going for computer generated or not yet)

Did an alien with a gun today. Learnt how to do a basic walk cycle.

I'm kind of short of time, I might have to skip or take it easy on the party tomorrow night :/ At least I have two models now, in case of extreme shortage of time it should be possible to make a game with only those ;)
