I love the gameboy aesthetic! Very metroid by way of kirby. Even the names of the areas are charming. I didn't make it to far into the game, I need to git gud, but I had fun with the parts that I got to see. I feel like, and this might just be me, part of what makes a metroidvania a metroidvania is that the upgrades change the way you interact with parts of the world. Since in Grapple you get the grapple after just a few short rooms there isn't much room for re-contextualization. Maybe holding off on giving the player the grapple and allowing them to play through some of the game without it would give the game more of a metroidvania feel. I don't know, I just love games like this that make you think about genres in a new light. Thanks for the cool game!
