Oh my god...
I haven't logged in on Newgrounds in a while, but I do now, just to tell you that this sucks at the highest possible level of suckism.
Let me explain...
The music? Crap! If what you want is JS Bach played on electric guitar, at least use Yngwie J. Malmsteen, this guy got it right. Everyone is giving you good marks because of the music... but uh... you didn't even do that music! People, think a bit before you rate. And you, buy an Yngwie Malmsteen album and change your mind.
The animation? Dull, plain boring. Just two blobs playing guitar, wow. No background (except one which has no elements and never changes), no action, nothing!
You look skilled, so try and do something better next time, I've definitely wasted my time watching and reviewing this... -_-
