Watabax is the final unlockable character in the alpha version of the game, and, when you first create his character, he seems insanely weak.However there is a simple trick to using him. The shift key. Doing tricks, or grinding/floor/wall sliding, will build up the energy meter. Wata appears to need a small amount more of the bar filled to activate "Hoverheat" mode. Once this mode is active, however, he gains stats that are double (at least, as far as I could tell), to that of the basic gamer in Hoverheat mode. If you upgrade the "energy" stat, this boost will increase even more, and, combined with some upgrades to speed and jump, he becomes the most powerful character in the game, at this point in time, at least. I found myself needing to adjust sime jumps, because I was overshooting propaganda, or ledges, but that is worth it, considering how easily you can scale buildings, or make jumps. The only real error that I have found with playing as him, is when you are carrying a gameball. Because carrying a gameball makes it impossible to do tricks, it can be difficult to get to where you wish to go, especially with secuboxes on your, er HIS tail.
TL:DR version, use the shift key every time you jump, just before you jump.
