Learning to Code - Lunar Pong

I appreciate the help @oldsoulnewb I definitely needed more guidance with the Markdown Language limits.

That said, I spent the past week working on this Pong Game. I have to figure out still how to auto-reset the "asteroid" and keep a score. I might work on the menu next. We'll go for a dry run and see if I can embed it on my Geocities website. If I can I'll edit this post and in place of what I'm writing now I'll put the link.

Feel free to use it as you wish. If you edit this to anything cooler please tag me in it, so we can nerd out together.
