I just purchased and installed the Linux version, so it's out. The site is weird about it though. When you purchase it (from a Linux machine) it tells you that the game is not compatible with Linux. After purchasing it the game does not show up in your list of titles if you restrict it to Linux only titles. However, when you go to downloads for the game it offers a Linux downloader and it installs in Linux and the installed product runs (at least on what I have installed - Kubuntu 22.04 at the moment).

I want to report this as a bug to the website but I can't seem to find the proper channel for that, so I'm posting it here.

Thanks for the info. Weird indeed although i'm just happy there's a Linux version one way or the other.
