First i used 6.3-8 version and it crashed when entering the computer, which is main part of the 'game'. Then it worked with proton-experimental and i could play the game. but when i went for another try it then crashed when using the door. However I unlocked all achievements and think i played all game, but there were 2 crashes for me. Still the game runs good when it does run and you can play all game without too many problems.
