Using physics to adjust the reflector is an interesting idea, but in actual gameplay, making even a small adjustment to the angle can be very frustrating. Unexpected meteorites that reflect off the surface might disrupt the previously set angle.

I agree that it's a generally fun idea. I think there is also enough control over the satellites to make minute adjustments. It's just a bit tedious to wait for the slow shots to connect. It would be more fun if they moved a little faster, so you don't have to wait too long.
Fun to play, but I also wonder... why is it so large? 1.6 GB when unpacked :O
