If you add items to use for puzzles and things like that this could be a very could silent hill/ Siren type of game, even if its short, the content you add makes the difference, very good ambient environment
You're definitely right, maybe in the future. creating game elements isn't my focus atm because I'm just focusing on visuals and how I can make the scene look. But soon i'm thinking of adding some elements of discovery, like secret areas etc
