Asked about this one before the boards died, but still don't know which game it is. It was a first person RPGish game (think Wizardry, but I'm pretty sure it was not Wizardry) for the original Game Boy. The main gimmick of it was alchemy. You had to gather up different alchemical ingredients (tin, copper, sulfur, etc) to fuel your spells. Nintendo Power had a walkthrough of it way back in the day, I remember
