Very commonly games have various items you can only use for one attempt (without reloasing save file) resulting in it being way too tedious to make multiple attempts at some hard parth of the game unless you are going to handicap yourself.
In super mario world items you get in one level will carry over to the next level you play and you also get big after getting a checkpoint.
In Zelda you can get bottles with healing potions but those bottles are often tedious to acquire at least if you want to be able to fully heal your character (rather than getting say 7 hears of healing).
In genchin impact you can make food that can be consumed later for more health, unfortunately getting said food is tedious and because it's a game constantly connected to a central server you cannot reload any save file to try again.
In code vein their are various items that can be used during boss fights that will not replenish after you die. Those items make the bosses way to easy (i never used them for that reason).
The general theme here is that when you die you do not actually get back to a state of the game you saved earlier, instead despite you dying the game actually progressed forward which is a bad mechanic but unfortunately very common.
