I don’t exactly remember the mechanics, but wasn’t there some heart or potion you could get to extend your hearts, but that consumable didn’t replenish? I remember using one early in the game and then realizing I should have saved it for one of the final dungeons. I don’t think I actually ever beat Zelda II and rage quit after realizing it was too difficult for 12 year old me.
