The idea here is really promising, I really like how dark you made the atmosphere having the flashlight and the enemies the only source of light
The doors aswell are really well designed and add a lot to the feeling of the game, it sounds also really good
The main problem I have is unfortunately polish, the game crashed twice when I tried it (when I respawned after dying) and the death is a bit abrupt, maybe some fade in to make it smoother
Still, I'm sure this could be a great game if expanded!
