Crazy Earth

It is a 100% real 3D gaming, based on OpenGL 2.0. In the galaxy. earth is turning around as it does every day, around it there are 12 stars trying to hit it...
1. Select your target country to be hit
2. Use your finger to change the star flying direction, or move your finger on earth to turn it for better hitting the target
3. count the total hit number to the target country. if you can hot more than 10 times out of total 100 hits.
4. you win.
5. select another country to continue..
As country size and location of the country, some of them are relatively easy to be hit, some no..

The space the environment is a frustum, the front of it is the screen you see, all stars and earth keep in side this frustum. when the stars trying to flying out the space, it will be bumped back as bumping theory saying...

Stars: touch it and fling your finger to speed it up in x, y directions...
Earth: earth origin is fixed. but it can been turned, put your finger on it, and move, you can turn it to any direction which you consider to better hitting your selected country...

3D drawing technique is used, bumping theory is used too.
