A family of retards on a collision course with slapstick wackiness!
The dark, twisted brainchild of Edmund McMillen and Caulder Bradford.
Another Koopa game, sorry Mario! That's right! Another Koopa Avalanche game! This one is WAAY better. It was finished in ONE DAY AFTER THE RELEASE OF KOOPA AVALANCHE but released a day late. This is basically the same thing as Koopa Avalanche, but with jumping, difficulty selection, and levels.
The directions and controls are the same as the last game, just dodge the spikes and other new enemies, including goombas, thwomps, fire, and much more. The controls are somewhat different, just left/right to move, down to duck, and 'P' to pause and 'O' to unpause and now use up to jump.
Once again, the secret level can be found by pausing. Have fun!
