THIS IS SO GOOOD!!!!
I can't believe this works on actual hardware. Seeing the Gameboy font , and the color palate, the limitations, it's so nostalgic for me. And I don't know how you got such amazing detailed art to work on the Gameboy but you did! The day mini-games are neat with so much charm to them, and planning your week is a really interesting mechanic!
And I'm really impressed with the way you wrote Neuro, it really feels so much like her cheerful demeanor that's paired with roasting ability is present, and the way she interacts with the other characters is really neat. I laughed at the "tell Vedal no" scene, and the hangout with Evil is so cool. It made me feel nostalgic too, especially with the references to current things getting rewritten by things of 1997.
That whole mystery has me very intrigued. I'd love to see more of this, if you decide to continue working on it I will definitely play again!
(Also, the fact you did THIS MUCH in just three days is insane. It's a shame the lack of audio dragged down your rating in the contest...)
