What it does

Jmon's Extended Mechanics adds a set of small features that extend the vanilla game, drawing on the style of Quark and other vanilla-plus mods. It adds new biomes with their own blocks and items, and changes gravel so it can be crafted from flint, which opens a progression path. Installation covers the server and each player's game. Files are published for NeoForge 1.21.4 only.

The author describes the mod as updated regularly, with releases roughly monthly, and a documentation page for specific features is still being written. The mod is released under All rights reserved and is not open source.
