Pong (itch) (FinniKey)

This is my first time making a game. I thought I'd start with something simple, so I chose Pong. I found a YouTube tutorial, but it was made in an old version of Unity that still had JavaScript functionality. I followed along and did the best I could converting it all into C#.

It's not particularly impressive, all things considered, but it's Pong. How impressive can one get. You know what I'm saying?
