Hi! I've just uploaded a desktop macOS version of the game. The desktop versions look to have much better performance and less stuttering.
If you'd like to give that a go, you can download it from the game page.
Once you've downloaded it, the instructions here will tell you what to do (since its just a jam game, I haven't signed or notarized the exe, so your mac will warn you about running it): https://docs.godotengine.org/en/latest/tutorials/export/running_on_macos.html#ap...
Thanks so much for checking out the game, and sorry for taking a while to upload a macOS version!
