First half: funny puzzle game. Second half: brilliant pseudo-philosophical walking simulator. It's way better than Prey in how it makes fun of perception and reality; and some sequences are so good that once more I cannot but think of how Control is tragicomically weak and trite in playing with both.

Spoiling quote:

In a few minutes, you'll be back in the real world, and some part of you will say that none of this was real: So how could it have really meant anything? But - just like the power of perspective itself - it will have been as real as you believed it to be.
