I found a nice app, Happy Face Popper. It's an action shooter where you control the mysterious character with the unique functionality of iPhone / iPod Touch. You can upgrade your shots to take on new challenges and destroy all bouncing targets to clear the stage. There are two modes of controlling: Flick or Tilt. Choose either control mode at the 'Option' screen in main menu. It looks really cute and it's only $0.99. If you're interested I can upload a demo video so you guys can let me know what you think. Thank you!!
