It was my first game, so i never knew how to do sounds in GB Studio...
PLUS, im incompetent at music, still even to this day.
Several months ago I found a Casio keyboard at a flea market and I learn how to play certain things on it. My musical skills have gradually improved since then.
Oh and by the way, I forgot to mention something I was curious about when I played this - how did you get the sprites to have more than 3 colors?
