An interesting and fun game.
This game did not release a native version for linux for some specific reason? I saw that you had another game with native support for linux.
We did ship one game on Linux because Unity offers it as an option, but we found that supporting Linux was taxing, as we don't use Linux ourselves and depend on players troubleshooting issues themselves. We don't have a regular Linux focused collaborator on the team. Since we couldn't playtest it locally or solve most issues ourselves, we didn't want to offer subpar support like that on future releases.
