We just released our game today on the App Store. It uses Cocos2D v2.2 (and Box2D), so I want to give a big thanks to the community here - we relied on many of the posts here to solve problems, especially those related to iOS updates!
Please check out our preview video on Youtube and our website for more information and screenshots, or just head straight to our App Store page.
Our game is called Psyklops Arena and is a unique and challenging action/arcade game. While on the surface it looks like a twin-stick shooter, we actually use a touch-based control scheme that gives the game its unique feel.
I really hope you guys will check it out, and thanks again, really.
