Meh, not bad.
I thought your game was allright. The grpahics were really kinda cruddy, I mean even with pixels, they could have been better. I liked the story-line but I didn't really like the gameplay. Level 1 was really hard, and the game itself is really tough to beat. I think in the beginning the difficulty should be a bit lower. The colors and effects were cool. The powerups helped with the game, but there weren't nearly enough.
P.S. To the person below me, the title screen says
"WARNING: This game contains rapidly flashing colors and images. Play at your own risk."
so there should be no reason to give it a low score due to the colors. There is a warning, and so if a person plays this and gets a seizure it is their fault, not the programmers fault.
