The Good, The Bad, and The Verdict
THE GOOD:
-Guitar Hero is fun
THE BAD:
-Extremely poor sound sync
-Minimal art
-Near-total lack of actual animation
THE VERDICT:
"The audio gets out of sync SOMETIMES?!" There was almost a ten-second gap at the end of the tune! I know that some problems in Flash just can't seem to be solved, but when it's THAT big, don't post it here until you can do something about it! Remember, NG isn't here for nothing but "sketchbook" clips with little or no point or quality.
As far as everything else goes, It's not exactly the worst thing I've ever seen, but it's certainly not the best. Your art (what there was of it) had potential, and you could really make some good stuff in future, but you've GOT to figure out those sound issues.
