Nothing is for free! You thought that beating minecraft costs nothing? Now it costs your life! Want to break a tree? -1 heart. Want to walk somewhere? -1 heart.
I saw a youtube short about this mod but he didn't actually release the mod so i made it myself. Its recommended to have some way to disable the menu blur as since the update, the text that pops up if you need to pay a heart gets blurred without it. This mod works with friends... and somehow in creative mode too. This mod is meant to add a challange to the vanilla game. If you have any problems with the mod, just let me know!
You can set your maximum hearts in config which works for all players in the world.
If you want to reset your heart cost just type /heartcost reset
