The team of Jeff Lange, Michael Phelps, Cameron Banga, and Jeff Greco recently developed a game, Tap Blaster HD for the iPhone App Store and soon it will be released for the iPad App Store! 
"The game is kinda like Pong in space with multitouch. You defend your home planet using a paddle with one finger while taping on screen with another finger to shoot missiles at your opponents planet. It's got an endless single player mode as well as two player head-to-head on the same iPad. Definitely think the two player will be a killer feature for the app, because it will provide a way for people to show off their new iPads to friends as well as show what types of new games are possible on the device. You definitely couldn't do a game like this on the iPhone or any other device, because you don't have a touch screen big enough.

We've been approved and are ready for sale, so we'll be on the device Saturday morning. Plan on releasing at only $0.99, but that price will probably be a limited promo for a couple days after launch and then we'll move up to $2.99 or so."
We spent 5 days on the game, which is kinda crazy looking back at it. We had a bunch of hurdles, mostly since we were going to school full time and worrying about tests. we've never built a game before either, which made it for an interesting experience when we ran into a couple problems. We had a computer crashing problem when we were about 90% done with the game too, which made things interesting. Throw in the fact that we never actually got to play the game how we've designed it up, since it requires two hands to really play right and we've only played in on a computer with a mouse. It's been an interesting week to say the least, but we're super proud of it and can't wait to play it tomorrow.
