Hey.
I wondered how to make this interactive arcade or more precisely arcade game that you can play. Is it like the UI or just a 2D game?

You’d make it the same way you’d make any game in Unity. Just put it on a layer, or set of layers that your main player camera cannot see. Render the arcade game to a render texture with a second camera that only renders your arcade game layer. Then use that render texture on the screen of your arcade machine.
