Defence of Earth

Earth is being invaded by monsters! Shoot them down with your cannon before they can reach Earth. The game has a "missions mode"(adventure mode) and a "defend Earth mode" (endless).This is my first Android App I have published and I plan to add more levels to the "missions mode". Feel free to give me feedback so i can improve my game.Bonus: No adds.Recent bug fixes: -Fixed some bugs causing dead things to not dissapear correctly.-Fixed an issue causing two icons to apper on the android.-Birds has been replaced with rocks (asteroids) now.-Been working on a new kind of level moon defence. (Try it out by clicking the vents in the mission rooms if you want (hidden)).-Changed name "Defense" to "Defence".-Minor bugs.Thanks for trying out my game and as always feedback is much appreciated.
