Very nice! Sable was actually the first game I played through on Bazzite myself!
Game's a bit janky (it was janky on Xbox too, when I played it there years ago, with exploration stuttering so badly I vowed to return on PC later), so it was a little stressful in that I wasn't sure if the issues were due to the game's code or something with Proton, etc😆
But overall a wonderful experience, and an impressive indie debut. I stuck with it until I had all masks this time around!
