Took me a while but I finally got this working on on my Mac ;; I know I could have watched a playthrough in the time it took me to set up everything but I feel this is something I really have to play myself - wish me luck!
(also if like me you keep getting the “unable to find *audio*” error message on the title screen - for me this was because I extracted the zip file. I’m not sure how it works but everything plays (music and all) and saves just fine by running the game file from the original zip folder.)
