Just something that I thought would be interesting to do. Basically if your player is idling he looks like he's shifting to stay comfortable, looking around, or doing something with his hands (or maybe even breathing...yeah I know they are plastic legos) Sort of like what characters do when you leave them holding still. Maybe a more pronounced walk and more player sounds, like gasping, grunting or even a noise the player makes while jumping. (besides the ever recognizable boing)
