Description
Deploy orbiting defense satellites to destroy all threats enroaching Earth - be it stray asteroids, comets or the mighty alien fleet!
How to Play
*Objective*
Use orbiting satellites to protect Earth against threats from outer space.
*Summary*
Build defense satellites/turrets to destroy incoming threat. Unlike your normal Tower Defense game, your turrets move in an orbit around Earth.
The only control you have is to *pause* a turret in its orbit by left-clicking on it and holding down the left mouse button.
You can also press the number key associated with the turret (lower-left corner) to select. Hold down the key to pause it.
You may only pause one turret at a time.
*Credits and Health*
You can only hold a finite amount of credits. The maximum threshold can be increased by upgrading Earth.
You can also repair Earth 50 HP at a time by clicking on the Repair button. However, the cost to repair Earth increases each time you use it.
*Building Turrets*
Use the menu on the left hand panel to build a turret. Or use the hotkeys below:
P - Particle Cannon
L - Laser Turret
M - Missile Turret
D -Distortion
E - EMP
S - Solar Satellite
*Upgrading/Selling Turrets*
Turrets can have up to 4 levels. Select a turret to upgrade it or destroy it
*Game Ends*
If you survive all the waves, you win! If Earth's HP falls below zero, Earth is destroyed and you lose.

Is there only one way to beat this game? If so what turret goes where?!

Wow, really really good game... I would just say two things: the font is kind of hard to read, and the repair rate, even on casual difficulty, gets out of hand very quick it seems like...

anyhow I think to much money is spent on repairing, way to expensive or it should auto heal over time slow, but still it would make a difference. Maybe the solar could also heal 0.5 per second or something

Not getting any credit for the solar. I have three and I'm still at 1.00/sec when according to the description I should be at 2.5? Other than that, a speed up button please please please. Fun game! 3/5

Please add more slots so that we can cover the whole are and not have to deal with large gaps over the whole planet ( by more slots i mean slots that go similar directions). Just add like 6 vertical slots, it would be nice. great game and I see a lot of potential. Perhaps you could add a way to take over neighboring planets or the moon to add more slots for turrets. Or build a space station that sends out fighters.
