Focus more on the gameplay and the quality of the map. Then worry about the 'killer' and make it interesting.

I recommend you take a look at Identity V. Despite being a Chinese game, it has a similar atmosphere. Or maybe try Slender the eight pages. I'm getting familiar vibes from your photo

oh damn I played this before ur doing everything right don’t worry I event checked console nothing errored

dont just have jumpscares for horror be creative with how your audience gets scared have like slow build ups its hard to explain

Add a story or secret lore to find

Change the name to something less generic

Looks awesome! A good tip would be to add good music and ambiance. Sound is the best way to trigger fear
