Yume Metsuki

Overview
Yume Metsuki is an English fangame made by MasterZere in RPG Maker VX Ace. It stars Karasu, a young girl interested in nature and flight (according to the GameJolt page). The game is still at a very early stage in development.

Gameplay
Yume Metsuki plays like most traditional fangames. Interacting with the top of the futon will bring Karasu to the dream world. There doesn't appear to be any effects and there's only one accessible nexus world, which is represented by holes in the floor. You are unable to open the menu due to a bug. Attempting to open the menu will crash the game with a script error.

Plot
There are some things Karasu can interact with in her(?) room and balcony, most notably a red notebook on the bookshelf, which Karasu says not to open unless her mother said so.

Once inside the dream version of Karasu's room, she'll notice that her mother's notebook is missing and she'll say that it might be in the tree out on the balcony. Interacting with the tree will make a voice tell you to find 15 effects and the notebook.
