Any chance this could have a zip version? Rar may be easy to open on Windows, but on Steamdeck/Linux the itch.io app (which is the easiest way to run itch games on a Steamdeck) can't extract rar. That means it can't be run.
Strangely the zip version isn't showing up in the itch app. Only the rar is.
I figured I'd give it a few days to see if it just needed a while to show up, but it's still not there. I don't understand why the itch app is refusing to show anything besides the rar. Doesn't make any sense.
