Note: beta 1.2 package re-uploaded. The 800kB zip only included the executable, which DID work, but the re-uploaded zip also includes example files, changelist and sdl2.dll..
Mac support is not planned at the moment. I'd basically need to outsource it, and that's not happening unless this starts selling surprisingly well. And no, having a mac version won't magically make it sell surprisingly well. =)
