Yes! You can run the iOS version on an Apple Silicon-based Mac - install it from the App Store.
Although not officially supported, it does run well (although it can be a bit fiddly as it is designed for touch screens). It is suitable for playing games with a physical keyboard and/or joystick.
You can add your own games and artwork much the same as the iOS version, except the folder to copy to is here:
~/Library/Containers/Spectaculator/Data/Documents
Open a Finder window, press Cmd+Shift+G and type the path above.
