I played this earlier today, its really good (though i never beat the octopuss), wanted to see what your hopes and views for the game are, you going for a more Zelda/Metroid (with dungeons, puzzles and items like the hookshot) style or as some above message mentions being dark souls-like (meaning big interconnected world with multiple weapon types and armour)
Either way great job, lovely style could look really pretty with blossom trees
