Here's my Pong Entry, it's not even complete, but it is pretty good for being incomplete. The "enemy" will probably be nearly impossible since it only follows the ball's y axis perfectly, and the scoring isn't very accurate, and the ball occasionally warps through the frame... but like I said, it's not complete. The main thing I like about my attempt at this is the simple use of sounds. Sorry I couldn't finish this in time, but if someone else wants to, I attached the ged and the data instead of an executable.
Controls:
Up arrowkey - Move up
Down Arrowkey - Move down
Right Arrowkey - Background change
Left Arrowkey - Background change
R - Remove Red value from background
G - Remove Green value from background
B - Remove Blue value from background
C - Make background's RGB values equal to 255
Enter - PauseGameOn/Off
Space - Start New Round (can only do if ball is off screen)
Again, I'm sorry I didn't finish this in time, but here's my attempt. Hope you enjoy it
