Overall I liked this one a lot, great game! Just a few things that bothered me:
- Jumping and grabbing a wall doesn't seem to work always
- At some stages the detection doesn't seem to work and
- when it works, it can detect the player through walls
- It's a little small. Could be bigger
But as I said, I think it's overall a great game (even though I don't see the theme). I especially like the idea of an unreliable narrator and the changing level.
