Last Defender

Last defender is classic ships mini game.

Defend the earth for you are only one remaining to do so.

Your ship arsenal has been damaged, you only have one cannon to defend all of mankind of multiple hazards, aliens, asteroids and their motherships, but its ok, one against an army is fair enough for a warrior of your level. 

NOTE: A course project that i upgraded for my GameDev portafolio, any feedback is welcome.
