Oh, good to know about Proton, thanks. Had no idea it was related. I'd test on Wine myself, but I'm poor enough I need to be sure it's gonna' work before I buy a game. I just know how good itch is for devs.
FWIW - we now give out a Steam key with every itch.io purchase, and the video issue is fixed under Proton, so the game should be fully playable under Linux.
