It's a real mess, am I right? But also beautiful.. in a way, you know? This game builds them. Or, actually, more like it "remembers" them. And the more times it remembers something, the less it does. Somewhere out there is a pool in an indoor waterpark, but in here, it's.. "remembered", just slightly wrong. Somewhere out there is a big mall and an apartment building.. I'm pretty sure that's how you get all of this. All these places, and um, rooms, buildings, misremembering themselves. In some ways, they're an improvement on the originals. For starters, they don't contain other humans. Can you imagine how good that must feel? I mean, there's no police. No crime, no rules, no economy. They simply… exist, like- like furniture. The best part... you can play through them.
Absolutely terrifying! It sucks that there aren’t more Backroom games that capture the Kane Pixel style instead all we get is just survival slop where you need to drink almond milk and run away from scp #9000. This game and the game they made a while back really capture the fear of “yeah you are stuck here forever and everything you recognize is somehow distorted and completely removed of life that leaves an eerie feeling around every corner! oh and you may or may not be ALONE…” would 100% recommend purchasing this!!!
I was looking for a Backrooms experience closest to what Kane Parsons created. This is it. Look no longer. You're here to explore and feel the walls breathe. It feels like walking through my nightmares. Theres a real sense of discovery and magic here that I havent experienced since playing the OG Bioshock. Amazing game.
If you are a fan of the Kane Pixel's version of The Backrooms, enjoyed the new Backrooms movie, or both, you'll get a lot out of this game. It's heavily inspired by Kane's take on the Backrooms, all the way down to the hazmat suit clad scientists. Not loaded with jumpscares - but very heavy on the atmosphere. Plus the VHS filter adds a lot to the experience, with the game having a fairly photorealistic look. Its a pretty impressive looking game, but I never had any issues running it on my system. Overall, if you like the Backrooms, especially the Kane Pixel's interpretation of it, give this game a go. You can get a solid few hours out of it if you don't rush through it!
