It's a realy gameboy game who i never played before XD.
I love the pixel art usage in this game, the map are big enouth for a exploration feells but not to big for a gameboy game.
I think you can put some notes to complete the music XD. But you care about making one and i will give you a good Rate for it.
I think you realy understand the meaning of "Era "Feel"" and make a game thinking in this purpose.
Great job! I realy enjoy it!
