I recommend making some custom systems for camera movement and normal movement (because the normal Roblox ones don’t really match the “eerie” vibe the back rooms has)
I’d also recommended getting more realistic textures for some of the textures so you can feel more submerged into the level.
Also, is there a monster/entity in the first level? I wasn’t in for that long, but I couldn’t find anything
The first map is a little too big and a lot of structures are repeated (which would be hard to change now that you’ve finished it)
The stamina bar doesn’t seem to go down (on mobile atleast)
Something that doesn’t matter as much is that you can tell the light noises are just a repeated sound (because of where it cuts in and out)
I also recommend you change the guis to fit the mood more. (Darker and more ominous)
I also recommend you make more visuals and sound so the person who’s playing can feel like they’re actually in the back rooms more.
