Even though I did not agree with everything in the game (specially with the Carl Sagan-esque philosophy about the Universe), I prefer to value the stuff I liked :)
The story is amazing and touching, surely the best I had found in any Flash game. Each character character has its own interesting personality and backstory, they are not just generic back-up characters.
The shooter is good and solid, it is not perfect but it is fun. Maybe I could go with a bigger variety of enemies, but the ones that exists are able to provide an enjoyable gameplay.
