Absolutely. The most likely course of action at this point will be to port the game in Love2D, which would allow me to keep most of the Lua code base. And Love2D framework supports Windows, MacOS, Linux, Android and iOS. So I would have a cross platform version on Steam and possibly even a mobile port down the line. In fact, since I work on MacOS, the initial port will technically be Mac.
Anyway I can’t decently have a 1-bit game not ported for the Mac :)
