This is a  2d space shooter tower defense game. The objective of the game is to survive for a maximum duration of time and save planet from onslaught of spaceship as long as possible. Your only help are 2 satellites  with shooting prowess. 

Controls -> Press [X] to Shoot, Press [Arrow Keys to move satellites]

Occasionally ships will drop powerups which have different roles
Yellow -> Extra score
Green -> Health(both planet and Satellite)
Blue -> Planet Shield
Red -> Swirling(You can press and hold X and move satellites to fire like machine gun)

Hope you have fun. Please leave a comment if you like my work. Suggestions for improvement are always welcome. :)
