Corallo

Overview
Corallo is an English Yume Nikki fangame created by Rukomura in RPG Maker 2003. The game has a recurring theme of ocean and underwater places.

Gameplay
Corallo is a traditional fangame. Your main goal is to explore the dream world and collect effects. Interacting with the window allows you to enter the dream world. You save the game by interacting with your bedside drawer.

Also available in the dream world are Quests. NPCs with a speech bubble above their head will give you a quest to fulfill. Completing a quest will reward you with Memories, an item that'll become important later in the game.

Plot
In the game you control Maya, a homesick wheelchair user. She cannot leave her room as her door is locked from the other side, implying that she may be stuck against her will. The only thing you can do is daydream, where you can explore and gradually uncover her memories.
