Just finished this game, I'm not quite sure how to process the ending.
The body-swapping time travel felt unique for sure. The puzzles with it weren't mind blowing but all made sense. The biggest complaint I have with the game has to do with performance, I had framerate issues in a few places even on low graphical settings which I imagine had to do with the frequent use of reflections (I could be wrong on this though, at the very least it was rarely detrimental).
