I just bought this but I can't seem to play it on arm mac? is that correct or is there an error somewhere on my part?
Hey, sorry for this! This is a common issue when exporting to Mac from Windows, Apple doesn’t trust the software. I would recommend playing through the Itch app which should resolve this for you. Alternatively, you can find a guide here to open the game anyway. There’s also the options of playing from browser or through wine. Apologies that this doesn’t work out of the box!
That's only part of the issue. The executable inside the .app bundle has the wrong permissions set (the execute bit is missing). Users will have to run
chmod +x "Snekcross MAC v1.2.app/Contents/MacOS/Snekcross"
(from the directory where the app is installed) before following the instructions in Godot's guide.
