The Door Of Thoughts

Overview
The Door of thoughts is another fangame which is an early work of Isasapiens, the creator of Me and Somnium. The game has many references to Yume Nikki, as there is even an effect named Uboa.

Gameplay
You play as a child named Michi, who is stuck in their room as they cannot find a door to leave through. Enter Michi's dreams by sleeping in their bed. To leave the dream, select "Pinch" in the effect menu. You can save the game through the pink computer in Michi's room in the real world.

The game features bits of dialogue when you interact with specific objects, for example, the effect-giving NPCs/objects. Some effects have special actions that can be activated by pressing the 1 key.

In order to reach the ending, collect all 9 effects (+ Pinch) and go to the room in the nexus that has 10 transparent figures. Interact with each one of them once. Wake up and exit through the new door that has appeared in your room. Finally, interact with the tree outside the house to finish the game and see the ending.

Plot
At first you know little to nothing about Michi, but as you find new effects, explore, read dialogue and see events, you come to understand some things about Michi.

Highlight to view at your own risk! [ During the game, you will find a diary written by someone who killed a girl with a knife. The author of the diary says the only solution for them is to commit suicide. It appears that the diary belongs to Michi, as the only thing you can do after they leave the house, is to hang yourself by the noose on the tree. They refuse to leave the garden through its gate as they think people will not accept them. ]
