I have searched the key word “arcade” on the wordPress.org for the plugin module, resulted answer is 7 items matched, and all failed after I installed and tested.
My idea is not working to play the tutorial game on my Blog (it’s a paid version).
This worked for me embedding from itch.io. thanks for the tip.
However, is it possible to point the player straight to the URL and have the game open in the browser? Not in an iframe, but occupying the whole viewport?
