Hey man, I have 3 computers in my house, all with both windows and mac, and none of them can run this game! I have no idea if the problem is on my end or not, but I just thought I'd let you know. I'm using iMac 2015, 2014, and a 2012, with bootcamp on all of them.
I've tried launching from the itch.io launcher, downloading the mac fix, windows 10, many different ways to try and play this game but I still get the problem that I outlined earlier.
They all have the latest operating systems, plus I've tested on a previous version of mac too.
No stress, I know making games is very hard work! (in fact I'm trying to make one myself, you're a huge inspiration)
