I really like this game. The only things I didn't really like were a certain lack of music, the most generic scary paintings in existence (maybe i care too much because i have a whole channel dedicated to art). Also from what I see you made a skybox in godot? huh? you could also go to WorldEnvironment > Sky > Sky Material > PanoramaSkyMaterial and add your texture. This should cover the whole thing uniformeley without some stars appearing closer in some places of the map. But having a skybox is a nice retro choice, so it's up to you.
If I had to add something else, dunno.. there is a certain lack of tiny details a player can observe by himself without the game directly telling him? although most of the things are blurred, which gives a dreamlike vibe?
