Take a journey through one introvert's convoluted mind as you work to cooperate with your past selves, recorded in time. As soon as you reset the clock, the level starts anew, except now there's a phantasmal double of yourself scurrying about, re-enacting your first playthrough move for move. Press [space] again, and add another one to the mix, this one also moving according to the steps you laid out. Some levels will place a restriction on the number of ghostly doppelgangers you can conjure, and these are the levels where you'll have to see just how adeptly you can work with...well, yourself.
