I'm playing it on Linux right now with the help of Lutris.
Thanks xybre, how is the experience so far?
Apologies for the long delay, I missed the notification.
The Linux-specific issues I've noticed have mostly been really minor. Linux had the game-breaking bug early in the game when loading between levels, but that has since been fixed.
The game is a little quieter than other apps and sometimes the samples are pitched incorrectly being slightly too deep. This might be a quirk of my audio system and a mismatch of the various sample rates in the game compared to the sample rate of my audio setup.
Lastly, this one is very minor, but the mouse cursor is weirdly dark and slightly less visible as a result.
The rest of the bugs I believe are just general game bugs.
(My framerate is fine but I'm playing on top shelf hardware.)
