Hey hey! Sorry my reply is so slow, I've been ill since before Christmas, and only just starting to feel well enough to get back on my PC >.<
With any luck, you managed to get it running, but if not, did you try some of the methods listed here? As far as I'm aware, at least one of them seems to work for most people. I don't own a mac myself, so I can't really bug fix or test stuff for mac versions personally >.< but all the stuff on that list is stuff that was suggested by other mac users who managed to figure out different ways of getting it to work for them :3
Someone even said that just downloading all itch games through the itch app on mac solves the problem 9 times out of 10, but since I haven't been able to test that myself, I can't say for certain!
Thanks so much for checking out the game :3
