Yeah I think they could have made it more obvious that the treasures were optional. I kinda figured they were since they're all golden statues with no description/meaning obviously attached, but I admit I questioned whether there'd be a meaningful payoff after all when the portal appeared in the treasure room.

Its also weird that the game doesn't tell you that you only need 10 fairies for ending B! The fact that it has a written message that says "100%" on the manual page made me think I needed all of them, but all you get for that is a treasure.
