BetterThanMite

The mod is a hardcore Fabric addition for Minecraft 1.16.5 that brings mechanics from BetterThanWolves into the game. A player starts with 3 hearts, which is 6 HP instead of the usual 20, and gains one heart for every 5 experience levels earned, so health stays fragile for a long time. Maximum hunger always equals maximum health: gaining a heart raises the hunger capacity, and losing hearts shrinks it as well.

Natural regeneration works only when the player is well-fed, and healing with hunger near its maximum costs saturation and food. Hostile mobs spawn more often at night, with extra zombies, skeletons, creepers, spiders and endermen, and witches and slimes can appear near players in darkness. Passive mobs spawn less often, so animals are scarcer and food is harder to obtain. Difficulty is forced to Hard, and switching to Peaceful is not possible.

Files are published for Fabric only, with builds across 1.14 – 1.16.5 in 11 release versions. The mod runs on the client, while a server can run it too, and the server is not required to have it. The code is released under the MIT License, and the project is not open source.
