There were some pretty interesting releases this week, and I think this list presents a decent cross-section of the lot. After bringing us a quirky puzzle game in the form of Tiny Story!, On5 takes us in a totally different direction with Indie Pixel. In this online only game you are a pixel, and you must work together with other players to form certain shapes before time runs out. If you prefer a more serene approach to things you might want to give Cloud Spin a try. This high flying adventure will test your skills if you want, but you can just as easily enjoy it by indulging in Free Flight mode and just enjoying your surroundings. Then there’s American Greetings, who didn’t so much provide the community with a solid set of games as they offered gamers a new way to pay. Buy an App Coin to unlock the game, and even folks without an iTunes account can “gift” specific games to their friends.
