Here you can check out my rushed chess code built with C# on UnityEngine
I didn't try to write this code clean. My goal was to write chess game as fast as I can. Not to make it easier for others to read
You can try to run this game in browser with this: WebGL built version
Even tho you can try it out in the browser, WebGL version might have lots of bugs like:
Not displaying text correctly or not playing background video at the start.
I'm not going to fix them, that is not the goal of this project.
For full experience consider downloading the windows version.
