Fun Game
Definitely a great game. I like how you put in the multiple performance options besides the built-in quality settings. I was dissapointed though that I experienced some stuttering on my Core 2 Duo (2.0 GHz) on the highest settings. If you could offer a downloadable .exe, that would be great.
Otherwise, awesome. Loved the idea of strategically placing turrets so you you can cover all sides of the planet.
