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.

Just a small fix for a reported issue. The number of stone walls bought in endless was not being reset on starting a new level. Due to this purchasing a stone wall or buying the sawyer tech could cause the current price to jump up to a higher amount than intended.

1.1.5 is a minor update with improvements to the camera, water, and skybox as well as fixes to several reported bugs. Changes: Updated Camera: The camera has been improved with the player now having more control over it. You can move in and out with 'w' and 's', up and down with the mouse wheel, rotate as before with 'a' and 'd' and holding down the mouse button will also allow you to look around from the camera's current position. This will allow players to get better angles on what they are trying to look at, both for block placement and for aiming volleys, catapults, and ballistae. Updated
