Yumecraft
by rebbystuff
Yumecraft adds three liminal dimensions to Minecraft, inspired by the Yume Nikki and Yume 2kki games, reached through sleeping.
What it does
Once a player starts sleeping, there is a random chance of being teleported into one of the three liminal dimensions. Dying in these worlds sends the player back to spawn, and items are kept. The mod is meant only for exploration, and it adds no other gameplay systems.
Yumecraft requires oωo (owo-lib) on Fabric, and Mod Menu is optional. Every player and the server need a copy of the mod. Its builds cover 1.21 – 1.21.1, and the latest Fabric file targets 1.21.1. The code is open source under the MIT License.
The author warns that Yumecraft is a beginner project with known bugs, and recommends backing up the world after each play session. Versions 0.3.x and 0.4.0 are incompatible with later releases, so an update requires starting a new world.
