Yume Nisshi (夢日誌)

Overview
Yume Nisshi (夢日誌) is a Yume Nikki fangame made by Zenmaigahara. The game stars Usotsuki, whose name literally means "liar"; not to be confused with Urotsuki, Yume 2kki's protagonist.

After version 0.02, Zenmaigahara discovered that a western game called "Blue Whale" had stolen some content from Yume Nisshi and Yume Nikki and blocked v0.03 upon release with several passwords to prevent other westerners from playing it. They temporarily discontinued the game after the passwords were solved and the game was distributed.

Some time after, they released version 0.04, also blocked with a password, the hint being "the name of the person who went to Onigashima with a monkey, a pheasant and a dog" in Japanese. This password is a reference to a story from Japanese folklore that was reused during World War II in Japan as an allegory for Japan's forces fighting against America, seemingly representing Zenmaigahara's anti-western views, which have been described as xenophobic.

Monetizing videos or streams of the game is implicitly prohibited. It used to be that even recording or streaming the game was prohibited, but Zenmaigahara got tired of replying to requests for permission and lifted the ban in v0.04.

Gameplay
Yume Nisshi is a traditional-styled fangame involving collecting effects and exploring Usotsuki's dreams. It has a more somber, lonely atmosphere than Yume Nikki and has more toned-down, subtle creepiness and very little blood. Like most protagonists, Usotsuki does not want to, or is unable to leave her room. Unlike many other fangames, however, you can obtain an item that allows you to save anywhere in the dream world.

In Usotsuki's real room, there is a door to a debug room that appears when she interacts with one of the corners of her room. However, as of v0.03, the door is blocked by a radio she owns.

The dream world is entered by sleeping in the bed, and progress can be saved using the desk. When entering the dream world, a screen with the writing "Go*d Night World" in broken, sketchy letters appears. The significance of this image and the reason why it appears are still unknown.

As of v0.04+, Yume Nisshi has 19 effects to collect and currently has no endings, but many events. As you explore Usotsuki's dreams, more doors appear in the nexus. An inaccessible room found in the game via RPG Maker hints at being able to switch playable characters.

Plot
None, as of v0.04; it is currently unknown why Usotsuki is isolated her in room and why she doesn't want to leave.
