Planet Defense

通过射击敌人保卫地球，使尽可能多的点尽可能。

Defend the planet by shooting the enemy and make as much points as possible .

How to play : Tap the planet to shoot rockets at the enemy invasion .

The only problem is that the planet is spinning and you have to aim as good as you can so you can defend it .

Don't think that it is easy, every level up means faster enemy , but in the same time more points !

Try to get your high score as up as possible .
