RRED early movement prototype

a scrapped, overpowered movement system in an empty box. I found myself jumping around in that box while thinking about how to make the movement not suck, though. so that's compelling. maybe I'll come back to this stupidly powerful movement some day who knows

controls - 

WASD / Space: duh

Shift: "slide" when grounded, "cling" when near a wall

Shift + space: long jump

space (on wall): wall jump

Shift + space (on wall): Long wall jump
