Really unique battle system request...

I'm not kidding. This is for a friend of mine. She is going to try to make a game where you battle enemies with... dancing. Yeah, its wierd. Anyway, here is what it entails.

-Each type monster will have its own song that plays during the battle.
-You have to use the arrow keys (And other keys for specials) and time the beats correctly.
-Little things will appear onscreen to tell you when to press the key.
-Each time you get a beat right, you do a certain amount of damage to the enemy.
-The enemy also dances, causing damage to you as well.
-Special moves (Such as breakdancing) will do more damage.
-She is making sprites to show the dance moves while in battle.

This will probably be insanely complex. But if you are bored and are looking for a challenge, please try this. Thanks.
And if you have questions, just ask.

i would like to play that

This seems a lot like a mix between FFR (Flash Flash Revolution) and a Blitz move. This looks awesome! XD If done, of course.

The friend who is going to attempt to make this game is supposed to join the forums tomorrow.

So anyway... Anyone interested in figuring out this script?
