Hey psymin! I'm totally down for getting the game on Linux, I just wanted to avoid having folks purchase the game only to find out that it doesn't work for their OS of choice. I've uploaded Linux builds of nearly all of our free games in the past because there's no cash on the line there, but I have very little confidence that any of them actually work.
If you're interested and meet the basic requirements to play the game (which isn't really an issue of PC specs, but more that you own two gamepads), I'd be happy to spend a bit more time trying to get a working Linux build together to send your way. :)
