Its like that game 'Try to fall asleep', I love that game I havent personally played it myself so this was actually a nice experience, I think the death scene was nicely done, and overall the tutorial and the gameplay felt smooth as well.
A note from a previous comment:
clamp the players rotation
Its not a big deal but its kind of immersion-breaking, other than that the game is scary and I think the theme is on point. Well done
