I enjoyed the gameplay, but it just doesn't vary enough for it to be very interesting for a long time. The turrets were often useless as they had such a small radius that I could just shoot them from far away. Also, the asteroids just drift around randomly - which i understand - but they tend to pile up behind the constantly downward-moving planets. Having gravity also felt rather weird, as isn't this space? Why should "down" be this way? Also, why are the 'planets' weird futuristic dome things if there are only sheep on them? Despite this, I think the idea has potential and I think if you were to make the gameplay more diverse it could be a nice game to play.
