I really liked this game. The first few goes were frustrating because I did not read all the text and did not appreciate how the evolution worked and later found that "guessing" was a bit... meh. So, a visual or text indicator (which doesn't even have to be permanent) would allow the game to be more enjoyable.
The movement is great! I love the animation of the guns. They have a real punchy feel to them. The universe also looks great and I love the xp/dot collection mechanism. The music is just awesome.
Very high scores from me!
