The backrooms is an large area where things that clip out of reality end up. It is so vast that is mostly empty, so far the game have deliver on that premise and I don't mean it in a cynical way. The levels feels disorienting and that coupled with the procedural feeling of the rooms give a strange sense of uncanny, uneasy familiarity which I believe was the original goal from the backrooms.
Now the bad, I see two problems so far. One is the lack of sound, ambience and noise are paramount in horror games to create the atmosphere, so far we get none from the backrooms game which I feel diminush the effect. The other problem is the scale, the room is too big which give the impression the player is a hobbit, I wrote a quick mod to change the player eye_height to '2.6' and the visual_size to '1.5' and I believe that gave a much more proper sense of scale. I would advise the developers to play around with that properties as I feel like the original Minetest values don't quite fit with this game.
Personaly I don't like the idea of taking pictures from the diferent places and would love if the devs expand on that idea some. Overall the experience matched my expectations for the backrooms.
Edit: Indeed there is sound, it was the humming of the fluorescent lights but it is a lot fainter than the player steps so it can be hard to notice without headphones.
Yep there are sounds, let me know if you have trouble fixing it.
And yeah I'll be changing up the polaroid system a bit, since it currently gives a bit too much direction. I want it to give the player just enough of an idea of where they can explore, but not encourage them to "beat the game".
I'll look into the eye height too, since although there are some parts of the map that will need changing (anywhere with 2 node high walkways), it probably does need to be slightly higher
