How did you manage to get it? all that happens when I open both versions is "cannot be opened"
Download the Crab Game (Mac 64bit) 1.29 version even if you have an M1 and run it through the terminal the first time, you will then be able to open it every time and it works perfectly well on my m1 macbook pro. I had to turn down the resolution because it was extremely laggy at first but now it's running at 60 fps with still a high resolution
