Cannon fire your pixelated dude through tons of levels of upgradeable cannons, boosters and power ups. Rack up the coin as your buddy gets gored, stabbed and slaughtered from bouncing around.
Aim the cannon with your mouse and click to fire. While he is flying, click on Pixel Dude to shoot him (up to three times) for even more range. Later in the game you can use jetpacks to give him a larger boost.
