“For me to support these versions, I would likely lose money because the user base is just not there (both of these platforms account for roughly 0.6% of all my Steam wishlists).”

That’s not a good metric to go off of bud. If I had backed this, I’d be feeling some kind of way right now. Unfortunately, as a Linux user, this is just par for the course. Devs promising a Linux Version only to cancel it later happens often enough that it’s almost expected at this point. Blech!
