Stuck In Orbit

You are stuck in orbit around earth. 

Defend it against asteroids and aliens as long as you can!

Controls & tips:
Hold left mouse click to shoot & aim

Build turrets by clicking on the empty slots on the planet. Might have to do it at the beginning as you have extra time.

If your ship loses its shield it can get destroyed. If this happens, you won't be able to defend the planet for a bit, but you won't lose health.

Getting hits on the planet will deplete your health (in the top middle). You lose the game when you health goes to zero.
