Have you played Casualties: Unknown? Well, I, with inspiration of this game, made this datapack that brings a realistis health system to minecraft VANILLA!

Alive

Alive adds a variety of things while you try to survive the world of minecraft

• Replaces the Minecraft Hearts with a new health system in your inventory
• Only 5 slots for your hotbar, and just 18 for you inventory
• You can get an arrow stuck in your body
• Your character suffers, with messages :3
• You have blooooddddd uuuu~ (And a heartbeat)
• And more!

I'm trying to add more things, but for now that's very much it!
