An interesting concept! The atmosphere was really tense, which is exactly what you want in a horror game, so you should definitely keep it and lean into it.
A few things I think could be improved:
- Key bindings. Sprint on Ctrl and Slide on Shift felt a bit unusual, since most games have it the other way around. And C to crouch is a bit awkward as well. I feel like it's better to stick to the convention - Shift to sprint, Ctrl to crouch/slide depending on speed.
- Mouse sensitivity. Definitely needs an adjustment slider. My character was doing 180s with the slightest movement lol
- Got stuck on the hole part in the first level for like 5 minutes. I feel like the ceiling is too low for wall jumping, but maybe that's just a skill issue.
But other than that, I think it's very solid for a week. Keep it up, and I'm looking forward to seeing it on Steam's front page!
