I'm sorry, but it's not very good.
Overall: 4
This just isn't a very good game. The main reason being that it's been done millions of times. Also, it didn't look like you put very much effort into it. You said something about dancing to the beat of rock but... There was no dancing at all. In the screen where you actually played it was just the arrows floating up and the pick you were getting... Nothing much really. This game was kinda boring.
Graphics: 6
They were okay graphics, but you definatly could've made some things look a lot nicer.
Style: 3
Like I said, this game has been done tons of times. I give you a three because you put a storyline into it.
Sound: 8
You did choose songs I liked.
Violence: 0
Well I didn't see any violence.
Interactivity: 10
Well it IS a game...
Humor: 0
I didn't really see anything funny.
~Some pointers~
In the screen where the arrows were floating up you could put some flashy stuff in. Make the text that tells you what kind of arrow you hit (Perfect, Great, etc.) more noticeable. A flashy and fun to look at playing screen would've gotten you a higher score.
