This is a very delirious level; disjointed, uneasy, and a pleasure to wander. A certain fascination with the cycle of mortality permeates throughout this level. Save points will have fragments of your character’s train of thought attached to them. (In addition to being despondent, this level is occasionally grisly and includes cussing – if such things would be awkward for you, be forewarned.)
Most of this level expects you to have all powerups – while it offers an implicit course in their use, you can crash past rather quickly once you know it better. (If you want to revisit certain areas, don’t pick up the eyeball.)
