hardcorify
by toeu111
Hardcorify changes the player's heart display as hours of play accumulate, turning the heart into a gameplay indicator tied to time lived in the world.
What it does
Hardcorify adds extra heart changes that depend on how many hours a character has lived. As time passes, the hearts shift color slightly, and after 40 hours the heart takes on a different look. A J key press shows the exact number of seconds the character has lived, so players can follow the timer without leaving the game screen.
The mod includes 22 heart textures for the stages of play, and it is built around a glass heart mode, where a shell disappears the first time the player takes damage. The author notes that reaching 50 hours without taking damage is hard. Hardcorify runs on client and server, so the server and every player need it. Files are published for NeoForge only, under the MIT License, and the mod is not open source.

What the author says
every time you pass a certain amount of time, your heart changes color slightly. 40 hours heart BUT IF YOU DIE, the heart will change back to the default color. This modification does not affect gameplay, so you can safely try to play with it on some servers idk.
