I submitted an update tonight for quadropong. It's mainly a graphics update, since I shipped with the placeholder graphics that I never got around to changing. I'm pretty happy with the look of the game now, check it out here. I really like the texture on the background, almost looks like carpet, and it really gives the game some depth. Now it looks like the paddles are floating on top of something, rather than in the void.
I also fixed (I hope) a bug where Game Center wouldn't authenticate a player if they left the game and came back without a restart (multitasking can be annoying sometimes). I think this bug may have cost some lost scores, which isn't fun when you finally get a good game going. We'll see if it crops up again, but I think I have it nailed.
I still want to add some more 'fun' to this game before moving on. I have three ideas for powerups, clickable buttons that pop up and float around that you can click on to help you score more points, but I want to figure out a way to add them without being too distracting. One is going to slow the ball down for a period of time, another will make the paddles bigger, and the third puts a wall up around the whole board, so you can't lose for a few seconds. I'm still brainstorming how to get these on the screen without being distracting, how to click them without losing control, and how they will effect the game when they go away.
