Pong, but without a second player! Use the mouse to control the horizontal/y position of your paddle. Hit the paddle with the ball to gain a score, and try not to let the ball go past the paddle, otherwise it's game-over! Click to change which side of the screen your paddle is on. Click and use mouse to use the menus.
I wanted to create a 'unique pong' game for the studio, and I came up with this. It could probably be expanded on, but I'm too lazy. This took me a few hours but really if I knew what I wanted to create it probably would've taken me one hour.
