That's extremely tall praise, saying it outclasses all of those titles as a Metroid-style adventure.
Well its got the best map design out of any of them, that's for sure. Calling it a Metroidvania is wrong, really. Most Metroidvanias try to make up for their map design by distracting you with RPG ELEMENTS, weapon/armor drops, easy combat, or basically just being a straight up action platformer with only a tip of the hat towards Metroid's map design. Like this is ACTUALLY a Metroid game.
