I will install all my bought Apps tomorrow and now I want to tell you about one of my favorite ones: "Doodle Jump".
In my opinion this is a must have App because it's a very simple game and it's great fun.
Once you begin to play it's hard to stop, so don't get addicted.
For those of you who didn't know this game I will post a "screenshot"
A short discription: In this game you have to jump up to different platforms.
You navigate your "Doodler" with the axis gyro from your Iphone or Ipod Touch.
