About this Mod

Superflat Plus

This Mod was requested by kg_boom3r to enhance Superflat Worlds. It expands on vanilla possibilities to allow you obtain unobtainables from Superflat Worlds since this was a request it's made to run on 1.20.1. It may work on 1.20 as well but no promises. If you are interested in this Mod you may make a request on the GitHub for a certain version (Only 1.20 and above)
