Features of the datapack:

-When you die, you lose an inventory slot.
-When you kill somebody, you gain an inventory slot.
-Custom recipe that gives you an inventory slot.
-Custom recipe that revives a random online dead player, putting them on 1 slot. (If no banned players are online it will consume the items anyway.
-If you die with 1 slot you get put into spectator.

This project is officially discontinued until further notice as I prefer working on my other datapacks.

I have not tested any other Minecraft versions and so they may or may not work with this datapack.
