In this simple hack, you enter a random area every time you enter a pipe. The levels are taken from SMB1, SMB2J and VSSMB, with a pipe mid-through the level to take you to another familiar area. The colours and graphics and also slightly changed to make it better-looking. Instant-death spikes are also included!
