I really liked the game. It's such a good mix of 2D and 3D. I was really intrigued by the story and managed to get a game over screen after collecting 5 of the paper pieces. I wanted to try a different way to see what happened, but I managed to softlock myself and was unable to continue.
The puzzles and atmosphere are good. I found it a bit difficult to use the flashlight when facing straight down. I was expecting to get spooked throughout the dark sections, which is good.
The wall climbing glitch was also very funny. I spent a decent amount of time mucking about with it to go out of bounds. I even did sequence breaking at one point. However, it did also cause me to get softlocked.
This one felt like a full game. Great work.
