Instead of Discord (for I'm a Free Software-centric guy), why not I playtest the game in future versions as a Linux player, and report my findings to one of your developers, if there is a Linux dev in the future, using Matrix via DM? That way, if I find anything wrong with it that's obvious, I could let you know that way.
For now, I'll use the Windows version on Linux Mint with WineHQ Staging, possibly Lutris ProtonGE build (stuff I don't think you'd understand necessarily well).
