Sure, let's just ignore the elephant in the room that GoG just doesn't do much about giving access to linux games.
It's been long enough to simply put a file on their servers and have it downloadable for people who used GoG as their service to access this game.
I guess from now on I simply buy directly from the developers, whenever I can, to avoid these situations. It's been ridiculous from the start NOT to have the linux versions for GoG customers directly available. All it needs is a simple download link. No software changes at all, noting. Just a link
well maybe you should check with the devs and find out why they are taking their sweet time getting the Linux version to GOG since GOG can't supply it without their consent or them giving them the Linux version to sell..just saying. Maybe they didn't get the memo that GOG now supports Linux(you know how emails can be lost and so on)
