Hypothermos

Hypothermos is a Fabric 1.21.11 mod where the world is very very cold and very very rainy.

Features

1. Frost bar. There is an additional bar above the hunger bar that measures how frosty you are. If you stand out in the rain, your frost will grow very quickly, if you stand below a block, it will grow less quickly. If you stand near a campfire, then it will reduce.
2. Campfires. They will go out in the rain, and they are not lit by default. You need a firestarter or a flint and steel to light them.
3. Firestarters. You can make them by putting an oak log at the bottom and two cobblestone on top. They can light a fire, and they might not light a fire first try. Also mobs can't breed because it is too cold for them to do so.

The project is built with gradle.
