Sulfur Cubed
by JustMili
Sulfur Cubed changes how a player-controlled Sulfur Cube behaves, with new limits on inventory, movement and damage, and it is a Fabric mod for 26.2.
What it does
Inspired by a video from Phoenix SC, the mod turns the player into a Sulfur Cube and reworks how the game is played in that form. Only one item fits in the inventory at a time, and an item already held in hand blocks picking up anything else. The bounce and slide of the cube depend on what the player is holding, and the body is only four hearts and one block tall.
Several parts of the Sulfur Cube's behavior are immune to falls, melee attacks, projectiles and explosions, and the immunity is removed while the player holds something. Vanilla GUI textures are altered too, and the barrier item uses a different texture to match the one-item inventory slot. Sulfur Cubed builds on Fabric API and is open source under the MIT License. Both the server and every player need the mod, and the server settings are read from config\sulfurcubed\server.properties.
The author describes the mod as a tool for a short session with friends, with extra challenge available by changing the config. Offhand use and armor equipping are kept by default and can be disabled there.

How it compares
Chaos Cubed Expanded is also a Fabric build for 26.2 and 26.3 but is not open source, and it is published under All rights reserved. Blocks Is Sulfur Cubes is Fabric-only for 26.2 and runs server-side only, so players join without installing it. Bouncy as a Sulfur Cube is an MIT-licensed option for Fabric, Forge and NeoForge, and the server is required while the client is optional.

but improves on a few aspects of his datapack and also making it a configurable mod! You can only have one item at a time in your inventory, and you can't pick up anything if you already have something in your hand,
