Cumrooms is a 3DCG adult adventure built in Unity by Moon Loom Studio. You play as a male protagonist in first person, noclipping out of reality into a liminal maze of rooms. The setting resembles the Backrooms, but the variant you enter may be the Cumrooms, filled with strange entities, parody tone, and adult encounters. Players choose whether to stay alert or give in to desire while navigating hazardous levels.
The current build is v0.9 Patch 2, released January 14, 2026, and development is ongoing. It runs on Windows, Linux, and Mac in English, without censorship. The latest patch is v0.9 Patch 2; the changelog entries provided cover fixes for objects spawning under snow or ice, invisible ducks, collision gaps, water traps, scene selection crashes, fullscreen behavior, and monster audio, plus a camera sensitivity option.
Developer's description
If you're not careful and you noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in.
Spoiler
If you are one of the unfortunate few who do end up here, beware that there is no such thing as certainty, and you may not even be in the Backrooms you thought you were. If your (mis)fortune has brought you into the Cumrooms, well, best to stay vigilant.
Don't be swayed by the strange yet sexy entities here; your cock and balls won't survive the trip.
But if you are brave, stupid, or just generally horny, then maybe this isn't such a bad way to go out...
