Fantastic game! The environment was very immersive, with lighting and shading fitting the story perfectly. The narrative was superb, having complexities not seen in most other games.
That said, I did find a couple of bugs in it. First, I ran into a bug when re-entering room 203. The door opened half way, closed, and wouldn't open again. I didn't encounter this again when I restarted the game.
The second bug is in the bathroom of room 204(?). In between the sink and the bathtub, there is a section of wall that doesn't have collision, allowing the player to walk through it and fall out of the world. This forced me to restart the game as well.
Some minor nitpicks I have as well are that the crosshair dot was abnormally large and that there were no mouse/keybind options that I was able to find.
I also messed around with the camera a lot on my first playthrough, causing me to unknowingly run out of camera paper. I feel as though limited paper is best suited for a survival game, and that being able to take as many pictures as you want would be better here. It would also be nice if there was an option to save the pictures taken (say, to a gallery/photobook that the character carries around or pinned up on a wall in a side menu).
All of these minor suggestions aside, this was a phenomenal game. I greatly look forward to what you make next!
