All features of this datapack are described in detail on it's official wiki! A beginner guide is also available.
Game design
While the player must overcome many new obstacles in the early game, they become easier to manage as the player progresses. The post ending experience remains mostly the same.
All obstacles introduced by the datapack can be easily managed in the late game. For example, hydration is essentially auto-managed when the player obtains a hydrating helmet.
This datapack is highly configurable! Almost any feature you don't like can be disabled.
Note
This datapack is currently in Beta and is actively recieving updates that fix bugs as I discover them.
When the datapack is close to ready for a first release I'll publish it on Planet Minecraft where people can leave their comments.
