[DF] Running, etc?

Current build

RxJS continues to cause me pain in my codebase. I think it is much better at normal internet tasks of streaming data from APIs then it is at streaming a massive amount of state changes in a game.

In the mean time... there are levels, a dude who runs, some interaction with doors, but no Win State, no Loss State, and no Deferred Actions. I don't think I'm going to do the deferred actions, I don't think there will be much benefit to it from a game mechanics perspective.

I'll be adding the victory and loss conditions, some additional obstacles, and some more animations tomorrow.
