~Keytar Hero Nice, but a few things
You've got the hang of the Guitar Hero cloning process. But a couple of slight improvements could be this:
In the tutorial it states to hold the keyboard like a guitar, which is fine.. *but* the keys 1,2,3,4,5 are inverted. That's just plain confusing! With the keyboard normally on the table it's doable though.
Then there's the notes, they aren't really corresponding with the music so to speak. You should check out "Crazy Deluxe Guitar Maniac" or something like that, also on NG. That one has perfect notes corresponding to the music.
As for a last thing, the graphics are nice, sounds aswell. You should try to use less of those obvious gradients, then it would really look nice ;)
