hey,
as a practice I created a quick short 15 minutes horror game that was a nice hobby project on the side.

this is my first game and FAAR from perfect but I am happy how it turned out. Please feel free to download it and give me your valueable feedback.
If you get stuck, make sure to read the README and remember use the grab functionality to your advantage to shove things through gaps and double jump WHILE being crouched is handy to fit through small gaps :)
