A Pong Ultimate spin-off, The Art of Bouncing started out as a simple drawing platform, and was that way until I decided that it needed to be Pongitized (that should be a word!). I added levels, platforms, and of course, the flashing dot. Move your pencil around with the mouse. Press Z to lower the pencil and start drawing, and X to lift it back up. Use Space to erase the lines. The object of the game is to get the Flash-Dot to the portal without letting it touch the pencil. If it does touch you, you get a Game Over. After you are going for 75 seconds, an evil green ball of anti-pong-matter will appear. If it touches Flash-Dot, Flash-Dot will disappear for ten seconds. If the Anti-Pong gets to the portal, it's a game over. Regular lines and the already-there barriers will do nothing to stop it. AND if it touches you, you're dead. But I'm not insane enough to not give you some assistance. At the same time that Anti-Pong appears, you get transformed into BluPen, which is able of creating Superbarriers that can stop the Anti-Pong.
TAOB was my first pen game and has several little glitches due to the fact that it was a test. The main glitch is that the ball will sometimes hit one of the lines and instead of bouncing off of it, it will glitch out and go through a line. This is more likely to happen with the thinner pencil-drawn lines, so it's best to layer them. Post the highest level that you have gotten to in the comments.
