A, D, and SPACE to move. Attacks: Z: Close range sonic screech attack. X: Long range poison spike shot. Press WASD to control direction. Q: Speed burst. (Oh, the irony!) Click the flag twice after any death. Combine attacks for coolness! (My favourite is Q+Z... Double damage! Hard to time right, though.)
For Pixel Brawlers Collab. I'm currently upgrading it's intelligence. You do take damage while attacking with Z if the AI is moving toward you. (About -5 health per hit.)
