Whenever a game that's even remotely weird becomes popular, the most common fan theory is that the game takes place in purgatory.
Well here we are, theorists. Real purgatory. Here, the devil administers 666 grams of hallucinogens, and you're forced to play capture the flag by yourself in a partially submerged maze while a little demon yells "YOU ARE IN WATER" until your sins have been fully payed.
I kind of loved it, though. In particular, I appreciated the old-school dungeon navigation. This is Bard's Tale for hardcore stoners.
