also I think i would make the only mechanics:
the block creator wand from alttp (to hide behind blocks)
the hookshot (the main weapon, to carry across gaps and bring enemies toward you)
Kojiro (always available, can use to fly oneself off ledges)
some kind of anti-hookshot, which would push enemies away rather than pull them towards you.
boomerang (stuns enemies)
Camo (decreases chance of being seen)
and what would be different would be that all the items would be available from the start, except for camo, which along with heart containers would be the only items found in chests.
