C to Erase Everything. Use ASDW keys I have to figure out good collisions/sliding to replace some of this, but this gives you a general idea of what I am trying to make happen. Be sure to jump and then shoot the ice path under and lead the mouse close in front of the character.
@TheLogFather @Psiborg Try to keep the mouse pointer close to iceman as you make the loops. He will slide along and around the loops.
