A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

We added a corridor to the left part of the two-way corridor, but it caused disturbances in other rooms during the section change. Its location was assigned to the section where it should be.
Added Difficulty to new players for better experience.
