Hey hey! Sorry my reply is so slow >.< I've been super busy with irl stuff all of October and haven't had a chance to go on my PC still (typing this on my phone while waiting at an appointment x3)
Firstly, thanks so much for checking out some of my games, and I'm glad you were able to play others without problems :3
Mac is a complete mystery to me as I don't own one or know anyone who does that I could borrow from to test stuff >.<
BUT... you're definitely not alone cos I've had Mac users in the past state various steps they've had to do to get different itch games to work while others seem to have no trouble.
It got to a point where I made a big list of everyone who commented and turned it into a megapost :3 I list it on all of my game pages, so you might have even have found it yourself by now, but in case not, it's this one here:

Honestly, none of what's written there means anything to me, haha. But with you being a Mac user, hopefully, at least something on there will make sense to you and will work! :3
Thanks again for your interest in the game <3
