Pong w/o Walls

This is my entry for the GMTK Jam 2018 with the theme "GENRE without MECHANIC". So this is classic Pong, but without walls on top and bottom; you hit a ball out, your opponent gets a point.

This is as simplistic as it gets, but I joined kind of late and didn't spend more than six hours on this one. I actually wanted to add an AI, but got caught up with something else; it shouldn't be too hard to play against yourself.
