IF you pay attention and wow, my comment that i spent a few minutes on making an hour or two back has already been wiped out, you will see Future Todd saying traveling back in time isnt possible. That is because this entire thing is a simulation.
*SPOILER ALERTZ* The most confusing game i've ever played. I've gotten all endings but somehow it all makes sense. Very confusing, 5/5, and somehow, once you get every ending and remember other endings when finding others, you may realize that Future Todd in ending #8, the earliest future point in the game, had planned something dangerous, and in others you find him in a bathroom, which leads to Todd or Angela finding Clint in the living room, a finger in one pocket, or Future Angela in the Bedroom, which the events in the house link to event #8, where Future Todd had planned something dangerous. A very confusing, and very great game.
