Liberty Boom is a game of fast reflexes, patriotism, and explosions. The game was conceived around the Fourth of July holiday this year, and contains twenty US city skylines and six original music tracks.

From a gameplay perspective, it's a little like Tap Tap Revenge, but inverted. Fireworks shoot up from the bottom of the screen in one of four columns - tapping the circular "tap zone" at the base of that column blows up the highest firework (which is designated by a rotating target marker).
Points are scored or lost based on how high the fireworks get before you explode them. The catch is that aircraft (planes, helicopters, blimps, and UFOs) fly across the screen, and hitting these causes you to lose points. Bonus pieces (2x, 3x, 4x) also float across. A crowd meter and crowd cheers and boos let you know how you're doing - if you reach the end of the level and the crowd meter is in the red, it's game over.
You can also use tilt control to adjust the speed of the aircraft, but be careful! Slow in one direction means fast from the other.
The game is currently in review and coming soon. I'll add the App Store link here as soon as we get it. The game will be released at 99 cents (USD) for a limited time.
Also, many thanks to Riq and everyone who contributes to the cocos2d for iPhone project. If it weren't for cocos2d we would still be writing our game and not waiting for it to be approved.
