Game release

Lost In The Backrooms: Day 100 · published 26 May 2026, 10:04 UTC

All newsPlayers around this dateRead on Steam

This will be the last update of the game so to make the game more enjoyable we made it easier to find the vent in level 1 (because many people couldn't advance because of it)

We also added Parallax occlusion mapping in some materials like the rocks of level 11.

We've decided to stop working on Lost in the Backrooms Day 100.

It’s not something we wanted to do, but honestly we just don’t feel like continuing this project anymore. We’ve spent a lot of time on it and tried to improve it as much as we could, but at this point it makes more sense for us to move on.

We want to say thank you to everybody that played it or gave feedback. It meant more than you think and helped me a lot while developing it.

Maybe we’ll come back with another game, I don’t know yet. For now though, this is it for this project.

Take care, and thanks again.
