All the features of the Fluidity playertype, but on rightclick when not grabbing a ledge, you jump in a direction. Just off the ground. So you can jump more forwards or more up depending on how you want to jump. Also walljumps by holding rmb against a wall of sufficient size before you hit it (and you bounce at a logical angle, not just go straight away from the wall, so you can start bouncing between two walls while still moving forward.)
This'd be awesome.
