And finally, here is a description from a stranger out there who has done a much better job describing the game than I have:

This game is great pickup and play fun and each of the in-app packs is not merely a re-skin but have their own unique rule variations and power-ups. To highlight some of the unique aspects:

Smiles (default): Can you keep popping the smilies in the dark with only their blinking eyes to match them by for bonus points?

Planes ($1 in-app purchase): Each match will cause a bomb to drop down on the city scape below so you'll need to make sure, beyond merely clearing the screen of matches, that you take out all of the buildings below.

Hearts ($1 in-app purchase): Besides matching hearts to make them disappear, you'll often need to mend the individual hearts before you can match them with another full heart. In an almost seemingly unrleated extra sub game, can you make the occassional bomb power-up blast in such a way so as to knock out a bird or UFO?

If you get the Gold version these in-app purchases are already included. If this weren't enough you can play each of these themes in three modes:

Race: Match all you can before time runs out.

Arcade: Match all you can until the screen fills up.

Free Play: Try to get the best score possible after playing through about 5 rounds.

Finally, while the game isn't a part of any social network, it has global highscores (divided by Week/Month/Ever) and boatloads of achievements (many theme pack specific like managing to set off three bombs in a single game of Hearts Arcade without hitting any birds or UFOs).

I'm very happy to announce the availability of my first Cocos2D title - Pop Fizz!

The game itself is an action-packed arcade adventure spreading across three world, supporting three different game play modes each. Match corresponding images and explore a myriad of bonuses as you race against time and strive to collect close to thirty unique achievements. Compare your scores to those from around the world through global leaderboards and seamless Twitter integration.

I've spend about two months working on this title and I'm happy with how it turned out. I hope you enjoy it as well and if you have any comments or thoughts I would love to hear from you!

On a different note, I must say that I was very impressed with the cleanliness and extensibility of the Cocos2D framework. Well done and thank you to everyone for contributing to it.
