The victims of lost sunny days: Eclipse

I was sorting through my old game discs. Among them, there were many games I played when I was a kid. All of them were labeled... All of them except one. It immediately caught my attention, and I decided to try playing it. What bad could it possibly do? There were game files on it. Nothing unusual, except for the strange name. I launched it. What is this? A children’s game? It's so cute and colorful, but why do I have a feeling like something’s wrong..? This ominous eclipse… ...Hey! My name is Sunshine! Yes, yes, it's me! Will you help me? What are you waiting for? I'm waiting for you.
