The Brain of Misery and his Spikey Turtle minions have it out for you, once again. You are the Toe Nail Wheel, the only known natural predator of the Brain of Misery, and you must use your unicycling and weapons skills to take down the Brain. Use the arrow/WASD keys to move and jump, move the mouse to aim, and click to fire. If you survive long enough, you'll have the chance to upgrade your weaponry. Destroying the brain in fewer rounds will yield a higher score, but surviving long enough to collect all the upgrades will result in a much more solid brain-kicking.
