Reminds me of Tetris Attack for the SNES

and you should get a ROM of it and play through it.

Although I personally wouldn't call this classic rock. :P

Pretty cool so far

I like your octave riffs, and it seems to loop around pretty nicely right now, so I can listen to this for a good while methinks. :)

Nice

It sounds pretty nice, repetitive as others had said, but would probably make nice background music, I'm thinking an ice / ice caves stage.

I'm no flash artist though maybe not. :P
