I 'effing HATE the turrets. I get one from a powerup OFFSCREEN, and it promtly redirects three meteors at me. It's not the rocks that're the problem, it's the dumbass turret AI.
Put in an option to mute the music!! Annoying as hell when you want to listen to your own music... Hint hint.
(Side note... the first time you face six cannons, it's easier without the sound. Turn off your speakers or something.)
@ DHH Claremont: It's VibRibbon. I LOVE that game... It's like this, except harder, with several forms to play as, you can generate a level from a music CD, the character is cuter... It was great. Hehe.
BTW, I used to live in a house called Claremont. Useless info.
