I was thinking to notarize this game to make it work with Mac Catalina, but then I noticed the current version doesn't work well even in my High Sierra (Windows one is okay). The major problem are "achievements are not triggered", and "depends on the language the game might not be able to launch on Mac." These are fixed now.

I'm very sorry that I'm very late to notice it. The notarization might take a while as there are too many build to update at my side. At the mean while, I updated the current game with renpy 7.3.5, so it will work fine with all Mac including Catalina.
Still, it needs to be notarized or it will stop working at 2020.

This game though, is not my prioritize yet, and therefore I will notarize it later after I've done with my others game.

Thank you very much for the attention.
