There is already a mac port of this game available on steam but I was wondering if that same port would be able to come here.

From my understanding the mac port on steam is not in the best state (doesn't run on the most up to date macOS), and we don't have contact with the developer we contracted out the mac port development to, so at this point we're not likely to try to release it on itch.

Also, I don't have a mac.
