For some reason it wont open on mac?
It should work on your macOS (I know it worked for other people). Remember to first extract the files.
Hmm weird because I downloaded the file and clicked the zip file and it led me to a folder that contained the game (it does this with all of the games I download from Renpy &it usually opens but..) but nothing would pop up.
I'm sorry tsunako, I don't have macOS and I'm not a very good computer specialist so I don't know how to help you :(
But I know for a fact that some people were able to open my game on macOS.
