Will there be linux support someday?
Idk what version of Linux you're using, but if you install the "Bottles" flatpak it lets you run windows games VERY easily. I just download, unzip and move the game folder to drive_c/Program Files/Games/ inside the Bottles directory. I've had 100% success rate in running Windows Itch.io games.
I use Bazzite (Fedora fork), but any Linux distro that runs flatpak should be able to do this.
If you want help just let me know the particulars and I'll try to assist as best I can.
