He's seriously the easiest to play besides springman.
Springman is tough to master. Springman is one of the best characters in the game because of his shockwave ability, but getting it down is tough. I would argue that Byte and Barq are the easiest to play, as all you need to focus on is mobility with Barq and when to use his jumps (which you shouldn't too much).
