The default controls are awful. You really only need one cable to maneuver well. You just have to sorta "spider-man" it.
Suggested controls:
Left mouse: attack
Right mouse: Right cable
middle mouse: can either go with both cables, switch blades or whatever you feel is best
space: Jump/gas
if you use middle click for dual cables, you can map the blade switching to E or R.
(Also P is the default for the options menu)
