To access the secret level, the player must head left on the 'Hell' level. Once this is done, a red screen will be shown. This will stay for a few seconds, then the level will load. Four platforms are seen, Jake is standing on the first one and Leopold is standing on the fourth one. Proceed to make your way up to Leopold. Once you do so, however, you will find out that he's really Leopold.exe. You'll fall through the platform and land on spikes. Then the game will close.
