I don't know my version or loader
A New World to move onto!
This mod introduces a dimension that can either be one of peace, or one of nothing.
- along with a few Items to aid you
The Current Items that are added are:
- Toy Knife - 3 AT
- Faded Ribbon - 3 DF
- Real Knife - 99 AT (1.3.8)
- Gold (Currency)
- Ruined Bringot (tool tier)
Recent Forge Version: 1.3.9b (1.20.1+ Requires Geckolib!)
Recent NeoForge Version: 1.4.2 (Requires Geckolib!)
The reason why I made this mod is because I could not find a complete mod that was for Undertale.
My goal is to have every single asset added that has an Undertale equevilant.
The current Planned versions are the following:
1.12.2, 1.14.4, 1.15.2, 1.16.2, 1.17.1, 1.18.2, 1.19.2, 1.19.4, 1.20.1, 1.20.4, 1.20.6, and 1.21.1
the versions activly being worked on are:
1.20.1, and 1.21.1
I also plan on porting this to fabric.
Note:
The Ruins is roughly 95% finished.
Snowdin is 1.1009% completed.
