What is the old computer game set in a castle/dungeon?

I would have played it in 1993 on an old computer. It would have been on a large floppy disk. The premise of the game was searching through a dungeon for a girl or a treasure. I know the character was a boy, but it is possible that you could have been a girl as well. I think that you were picking up flowers along the way or some other odd items. Also, you could turn into a butterfly at some point. I think turning into the butterfly was a good thing (not dying) possibly from picking up enough rewards along the way.
