It may be an issue related to integrated graphics, I'm currently unsure of a fix for that at the moment so you may have to stick to the web version.
I was thinking about tinkering with it in Godot if that's okay, does the github repository reflect the current itch version or is it an older release?
the github repository is very broken at the moment, im gonna be honest i had no clue what i was doing with github when i was making it, and I need to completely remake the repository.
