So a friend and I have been making our own version of Pong for the final project (real original, amirite), and we're pretty much 100% finished with it. We have 2 weeks left, so what I really want to do is just test it as much as I can to make sure that everything works the way it should, because I'd also like to publish it to the interwebs if it's entertaining enough. So, because I <3 you guys so much, I'm giving you the game to play and/or test. Most of it is testing the physics, but if you play this and find any other issues (other than "it sucks"), just lemme know.
You'll also notice that there is a benchmark tool in here. If you want, you can set enableTool to true, and the goal is to have the console print "hit" once every second. If your PC gets something really different, you can modify SleepTime to get it to that rate. If you have to do this, post your specs (if it's not in your profile) and the SleepTime you had to use to get it to 1 per second.
