In particular, if you got here via Two for the Price of One, you can use the Rocket Launcher you obtained there to jump over to the place I've marked 'Secret End' on the map. This grey pillar will take you to Electric Sheep Two, allowing you to completely skip two of the hardest levels, Acme Station and Post Naval Trauma, as well as two more somewhat confusing ones, Where Some Rarely Go and Thing What Kicks. Unfortunately, you still end up having to do Hang Brain, which is perhaps one of the most nightmarish levels ever conceived by man - those Purple Troopers eat you up, as I've realized, not to mention you get practically blindfolded every few minutes (or every few seconds, even) by big, flashy explosions. I actually had to turn the difficulty down from Normal to Easy just to get past that level on my latest run-through - and I got through Acme Station with my health still in the yellow all the way back from Poor Yorick!
