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.

Hi there. Now the pause menu screen has sound effects on it! A lot more pleasant (: And also the level selection system has been improved. Now you can select the level by its number and then press A (gamepad) or Enter (keyboard) to go to the level you have selected. You can also fast forward the numbers on the level selection by holding the arrow key. Thank you all and I hope you are enjoying the challenges at Mastho is Together :D

- Now you can perform a dash using the RB or LB buttons on your game pad; - You can get the game to fullscreen by pressing any button or key during the splash screen; - The app launcher icon has been updated. Now you can see the little mastho on a red background :D Thank you all for the great support and thanks to Pedro for giving me the suggestion to add the new dash buttons. PS.: Maybe you had lost your save files. Please let me know.
