Use WASD to slide around and click to use the grappling hook. The grappling hook pulls you to enemies or the center object. Have fun moving around with the hook and quickly slaying enemies. Your combo is broken if you get hit or wait too long without getting a kill. You have orbs that give you special abilities. space is for flame dashes and it has 2 charges and uses red orbs. "e" is for triple shot and uses the blue orb. "f"is for thunder sword and uses the yellow orb. "q" is for blade disk and uses the gray orb. "z" is for acid pulse and uses the green orb."r" is for psychic blade and uses the purple orb.
I recommend a mouse but a trackpad works too
