Drone Invaders - addictive space shooter game

Please test my new game, this is space shooter game built specially for Android mobile devices. Most other games include spaceship that you have to move around with your finger, which is usually tiresome and also makes your hand cover the screen. In this game, you control a gun turret, so there is no moving around, just tap wherever you want to shoot.

Maybe it's hard to explain with words, but the game is really addictive - once you start playing it's hard to put your phone down. I released it yesterday on Google Play.
