apple silicon is arm based, he will have to port the arm(android) version to mac then, possible, but unlikely, sorry.
He's using Unity. Building for Apple Silicon is only available in latest unity builds but it's gonna eventually be everywhere.
yeah but all you would have to do is update the editor to 2020.2 and then select apple silicon + intel in build settings
that makes it much more probable that dani could release a macos arm build as soon as he wanted. I doubt dani will update this game anymore but yes apple silicon support would be appreciated
