Too bad I only figured out that I could upgrade the graphics AFTER I fully upgraded my ship and finished all waves. Oh well. I'm really glad I played this game.

This was awesome, but it's kind of easy to get the badges if you're willing to sit there for half an hour just playing it over and over. I think in the sequel, more challenges should be added, like perhaps a health bar and losing a % of your cash if you die/fail or something.
