Good idea. However, the controls are confusing (speed changes randomly, although I think it is because of "being on ice"), the grappling hook has too long cooldown.

controls- very confusing,random speed changes suddenly turning on and of  gravitation.i also found myself not using the grapple much. it has a very long cooldown and half of my attempts to use it resulted in me falling. i would advise adding some sort of an indicator showing where it will move you.
