Yume 2kki
Yume 2kki is the fan-developed "sequel" to the popular RPG Maker game Yume Nikki. In this game you play a young girl named Urotsuki and explore your dreams, similar to Yume Nikki. The objective of the game is to collect the effects scattered in the dream worlds, which is also similar to its predecessor. However, Yume 2kki is much larger than its predecessor and is still growing, since it is currently under development (nevertheless, it is fully functional).
Story
You play as a girl named Urotsuki. Due to the many, many worlds of Yume 2kki and the four main endings, there are many theories, and it's really up to the player how they want to interpret them.
