Having a section in the extras menu for controls/tutorial is exactly what I've been thinking of, though I'm not sure if that's obvious enough. A lot of people might not check there before starting. Each character has a different special move, the one you were using has low AOE but higher strength and it gives you a burst of speed. Also, yeah the buttons are kinda wonky right now and I've been knowing about that. I have to go back and change them.
