Thirst

Just as with hunger, as time goes by you will feel the need to drink. If you forget to do so, your character will start to feel unwell. So think about getting drinks that can quench your thirst. The most common is the waterskin. The need for thirst varies according to the biome and what is being done.

Aging

Caves that are inhabited for a long time grow vines, stalagmites, and generate pebbles to make caves look more cavey and run down. This also happens in constructions made with previously unprocessed materials.

Cave-Ins

When very, very low underground you should bring a rabbit foot with you to avoid cave-ins from happening. Once a cave-in happens, the cave around you collapses with a deafening blast while blinding you in the process.

Hypoxia

When caving, there's not so much air to breath, and items in your backpack are felt heavier. Because of this, when low underground your character will complain and you'll fatigue every now and then.

Ambient Sounds

Sometimes while exploring a cave a creepy song will play or you'll hear strange sounds. A few examples would be water dropping, someone saying "oh" softly, or a spooky music disc playing lowly.

Custom Structures

Tiny little structures that spawn throughout caves to make exploring more interesting. Chests that can spawn in these structures contain items that you need to survive, so living only in a cave is now possible without traveling to the surface. There are currently 36 different structures, so finding two of the same is decently difficult to do.

Real Time

The time and weather within the game correspond to that of Paris (France). This rule is not applied in lobbies or in the mode Minigames
