I forgot.. to do Alpha Centauri, I'll have to use my own gravity system instead of the Unity physics engine.. but that gravity script worked well in the last game jam, so I think I can just recreate it...
and I would like to add in some 2D hinge joints to Crowley's arms and legs, to give him a ragdoll effect while falling... that might be beyond my abilities, since I've just not gotten hinges to work yet
