Good, but could have been more
It was a good game, cont get me wrong. But i think you could have added more to it. It was very easy at times, and i finished the game with 26 black diamonds because I shot through the gate in the sky. I think you should have added a poetic element to the game. Something like "You invaded this planet, killed everything living here, and you were supposed to be the hero." It reminded me of the Milgram experiment, because we were just doing what the authorities told us to do, without thinking twice.
