Awesome game, very fun to play and I like the movement of the enemy ships a lot! The game definately feels very finished, it has everything it needs up to a highscore list. The colorscheme is a bit too colorful for my taste, but not really that disturbing.
I think there's indeed some room for details, but frankly I don't think that's really needed with this style. One thing I did miss a bit, was a small explanation how everything works, eventhough after messing around you will understand the goal and controls in no time. At first I was shooting humans hehehehe.
Anyways thumbs up, i'm downloading you 'Robot Invasion' game now,
Cheers
