I will be honest here, I liked it better when the backrooms were just like a mysterious realm that was tied to our nostalgic childhood fears, instead of whole lore similar to SCP. But I really enjoyed playing this demo. I feel like if anyone wants to play a game about the backrooms it should be this one.
The game is mysterious, it has entities that lurk behind walls and appear in front of you only to be seen for a few seconds. The low buzzing frequency of the lights gives off that eerie nostalgic feeling. I liked how you added a small video clip, in the beginning, kinda showing the "family-esque" type VSH recording to the protagonist falling and ending up in the backrooms. I liked how you implemented voice audio recognition, but it feels like it didnt do much. I suggest that you have the player say something or do voice dialogue, in my opinion, I feel like voice recognition should be used more often. Other than that I enjoyed every part of the game, now I just need to wait for the full release!
