The best soundtrack I've ever heard on the Game Boy or any 8-bit system, and one of my most cherished video game soundtracks on any system, period. Some of these tunes still find their way from the depths of my memory as I gleefully whistle them from time to time. There are excellent "metal" covers on YouTube ("Breager's Castle" most notably), which proves how good those compositions were. It's all the more amazing considering the limitations of the original Game Boy or the fact that the whole game -- equally wonderful by the way -- was contained in a 128KB cartridge. And it was released very early, in 1989, when the portable console was brand new. I remember the manuel boasted that this game had the best graphic and sound qualities on the GB, and not only was it true at the time, but it remained true until the end of the Game Boy era for the music part, while very few games were as polished graphically as the action levels on this one, especially the magnificent "Dark Tower".
