I can remember I've been loading this game again and again because the music is very good. A few years later everyone was playing Tetris on Gameboys and I only thought "why the hell are they playing this old game on a handheld that not even has a colour-display..."
Anyway; it's best to play this version on a monochrome-screen because the music is too slow on RGBs. Also, the background flashes nervously in some very ugly colours.
