The not-so-secret trick to getting high scores in this game is to make sure that you fire the zorlon cannon so that you blast the Qotile while it's in flight trying to hit you. That'll get you a lot more points than just hitting it while it's slowly moving up and down behind it's shield.
The difficulty increases in relation to your score, NOT the number of levels you beat. You'll know you got to a higher difficulty level when the Qotile's shield changes color (I think the first change (to blue) is around 70-75,000 points or so)
