Very well crafted. I really like the gameboy color aesthetic. It has that Metroid 2 Return of Samus vibe. That being said, I do feel like something is missing, and I didn't always know what things did.
Thanks for playing! By "missing", do you mean the puzzles weren't intuitive, or something else? I know of a few specific ones that are pretty unintuitive (and I hope to fix in a post-jam version).
