Your mileage with the Linux version may vary, especially if using Wayland or running using Linux via ChromeOS. It gave me a compatibility error (in russian), then only opened in a tiny box. Enabling full screen works, but the game contents stay confined to a tiny corner of the screen (the styled cursor can move anywhere though).
I have not had issues like this in years with ChromeOS, but you can manually fix it to an extent with something like:
sommelier -X --scale=.31 --dpi=460 ./PMKM.sh
I played with the above values a bunch until I found something that didn't crash the game and looked ok. Note that I'm also on a 4K screen.
