I hate how the system makes you spawn in locations that are problamatic, to the point when you spawn you could possibly die again. It takes fast reflexes in game.
You know in Deep Sleep, when you put the code in the number pad and get the pick axe, run away from the Shadow Person, and close the door. In the end of the Deepest Sleep it's the very same moment of where you chase the guy, he rushes away, and closes the door. Isn't it possible that the Shadow Person possessed your body from the second and fell into a deep sleep and you somehow reclaimed your body which is the body you just took.
you easily lose track of yourself(the original) when they're are more of you, you can't kill ones that can't be destroyed(it's a pain fighting the blocks that are pushing you around you die when you get pushed into another block) which in turn makes the replicator block strategy fail if you're in a hurry(I'd like an extra turn due to them always on your tail), and you overthink on what the other blocks are going to do(personally I fail to defeat the four way moving block).
