Great little fast-paced shooter
I had a lot of fun with this game, but I finally gave up around level 38. Of course, I was playing easy mode, so it was a little too simple - I'll try the harder levels next. My only real complaint would be scoring...if I shoot two enemies together on level 2, I get 2000 points. About level 34, I had killed 6 enemies with a well-placed charged shot and got 6000 points. Maybe you could consider ramping up the points based on level/combo #? I just felt my sense of accomplishment went down, as the enemies got harder to kill.
