Someone else had this problem too, can you usually run other unity games in 3D without much issues? To be honest I'm not sure why this would happen, but I believe it has something to do with the shaders in the game and the graphic card
yep most other 3D/unity games (at least those I've downloaded from itch) are fine - but my mac simply doesn't do well on games lol
i just dl the game and i have the same issue, running macos v11.5.1. looking forward to being able to play it
