Adding any more colors to cycle through is practically impossible with the way I had to implement the one-button system so that it wouldn't break. What the Space bar is doing is essentially toggling a flag attached to the player, and the bullet collision logic is based upon whether that flag is on or off. It's more foolproof that way - trying to do the same with an integer value in Clickteam Fusion 2.5 is incredibly prone to breaking and a pain in the ass to work around. I appreciate the feedback, though. c:
