Secret level 5:
There is a secret level in Episode 1. After completing level 4 but before
advancing to the next level, go to coordinates 8,24 to find a group of
boxes. Enter the small room found nearby, which has a pair of adjacent
dumbwaiters. Block the opening of one of the dumbwaiters, then enter the
other one. You will enter a hidden area which leads to a transportation
booth that will teleport you to level 5.
