[GAMEBOY/GB COLOUR][UNKOWN] Difficult Dark Fantasy

There is a chance that it's a GBA game, but I remember using a square cartridge not a rectangle

What I think I remember from the game:

- zelda 2 kind of map, you go into an area and it had a mechanic similar to text-based adventure games where you choose an option for which direction to go. Generally used static pixel art in these areas

- was a dark fantasy/grim dark setting. no horror or gore

- there was a castle and/or a dragon

- I think there was a way to sneak into the castle from the dungeons/moat and use a torch to light your way

Hopefully notable addition: I want to say the game was a GameBoy game, but there's this nagging feeling that when you equip the torch there's colour, implying GBC. Most if not all of the game was black and white though.

Sorry this like all I can really remember it's a game I played a it tiny amount nearly 20 years ago because I kept dying when I played :(
