Saving Yello is a physics-based puzzler. In it, you flick a helpless goldfish called Yello back into his bowl of water so that he can get revenge on his 7-year-old owner by destroying her toys.

You have to complete this task over 50 different levels, each of which gives you the chance to bag OpenFeint and Game Center achievements.

Super Crossfire is a top-down shooter in which you use a unique switching mechanic to quickly warp your spacecraft between the top and bottom of your device's screen and outmanoeuvre enemy fighters.

Your ship can be augmented and upgraded in ten different areas, which should help you survive the 150 waves of enemy ships that'll attempt to take you down.
