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.

Version 1.0.4 Fixed an issue where the game would freeze on specific cutscenes. Fixed an issue where text would be displayed outside of the screen in German. Fixed an issue where the player would get stuck on some geometry. Fixed an issue where the player sometimes would get stuck in an infinite respawn loop. Fixed an issue where the player wouldn't be able to transform into a bird even though the related tutorial step was completed. Fixed several issues related to audio not playing at all, or not receiving intended effects. Fixed an issue where sound would play on full volume regardless of us

“I can feel it coming in the AER tonight, oh Lord And I've been waiting for this moment for all my life, oh Lord Can you feel it coming in the AER tonight, oh Lord, oh Lord” (freely adapted from Phil Collins) Although Phil Collins didn’t know about AER when he performed the song, one thing is for sure: AER is coming tonight! Rejoice and have fun!
