Break Block Break Bones

Each block a player breaks removes one point of health permanently, and the health loss stays after relogging or respawning. When health reaches zero the player dies, and dying restores health to its starting value, so a run ends and begins again from full health. The mod is built around this single rule, and its author describes it as a small experiment built on Fabric API.

Because the rule is the only feature, the mod works as a challenge setup rather than a set of added items or blocks. Players can use it on their own or on a server to play challenge runs, such as seeing how far a run lasts before dying. A known quirk is that the health display sometimes fails to update after a change; taking damage refreshes the display, so the visual issue corrects itself on the next hit.

The mod runs on the server alone, so players join without installing it. Files are published for Fabric and Quilt for 1.18.2 only, and the code is released under the MIT License without being open source. Fabric API is required on both loaders.
