CuteHardcore

This mod adds "enhanced hardcore" which can be customized. You can turn Hardcore on and off at any time as long as cheats are enabled (or as long as you have operator rights if you're on a server).
Set the number of lives from 1 to 10 (default 3) /ch maxhd "1-10"
Initially hardcore is disabled, to enable it enter the command /ch hard true
Also, after all the lives are over, you enter the “switch” mode and the effects “slowness 2, weakness 2, hunger”. And after you die 3 more times, you will become a spirit.

There is such an item as an “editor”, it will restore 1 life (cancel 1 death) the item can be turned on/off using the command /ch edit false (by default true)
Please write what you think about mod.

Command for 1.16.5   /chard

Improvement plans: add a display of the number of lives you have.

P.S. Vanilla hardcore should be disabled. Otherwise the mod will not work.
