Anyone know if the dev is planning on bringing the Mac port from Steam to GOG?
GOG barely supports Windows builds, so probably not. There's no publisher standing in the way, nor is the game old enough that they'd have to worry about converting it to M2 code...so it just seems they frankly couldn't be bothered to deliver to GOG.

I'd shoot a support email to both groups just in case they forgot, though.
