I don't know if anyone knew this, or if they ever bothered to check it out, but the Gameboy Version of Tetris actually has something somewhat secretive to it's music. If you pause the game while the music plays and unpause it, the baseline for the music seems to increase or alter itself. Just something I found a long time ago that I'd share.
I've heard several developmental stages of this song by PriZm and liked the progress he's made on this, however, it's strange that after he submitted this, it's like he disappeared from the face of the earth? Anyone know where he went, I've tried e-mailing him and such to no avail. Did he change aliases?
