I just released my second game for iOS. It's an iPad-only game that I developed over a weekend. After looking at all these awesome games available, I'm a little sheepish about telling you fine folks: but I will anyway.
It's called "It Doesn't End". It was developed using Cocos2D. What happens? It's a bank of LEDs and you try to keep the red lights from going off of the screen. It's super simple: like, stupid simple.
Oh, yeah, and it's free. So, download it and rip on it/love it/whatever it.
