HELP

A space explorer has found himself on an uncharted planet. Now he must try to send a message out into space, but must first deal with the signal jamming devices and aliens of the planet in order to escape. 

This is a tower defense game. It is in a third person perspective. Use WASD to move. Use Q and E to turn. Left mouse click spawns a turret, and right mouse click places a turret. Use the numbers 1-7 to switch the selected turret.
