I think you need some more practice
Well, ain't bad for your first flash, but I can't really say that I like it. Not that it was that bad, but there were some annoying things about this game.
First of all, the bunny moves very slow or the needles move to fast. It was impossible to avoid being hit sometimes. Maybe you should add a powerup so that the bunny moves faster or something that make the time go slower and the needles go slower as well. Second, I would choose some different music if I were you, I think the current music was a bit boring. Third, the whole screen turned red when I was hit, that was probably the most annoying thing of them all. At some moments I couldn't see a damn thing, please remove this. Fourth, the bunny kept getting bigger, because of this, it was even harder to avoid the needles.
Well the best thing about this game was probably the graphics, they were pretty good.
Anyway, overall I'd give this 5 out of 10, 2 out of 5. Like I said, it wasn't really that bad for one of your first submissions, but I think you need some more practice. I'm not really interested in the next parts, but good luck with making them anyway.
