I was wondering.
During exploring in the campaign, we sometime stop for a drop of puddle water. I've been spoiled by a game called Aywas which this is quite similar to LW.
When we drink or take a nibble at something, can it restore SOME stamina, not too much though because that is what our general food is for.
Balance wise, since we lose 5 every step, maybe just gain 5 stamina every drink. Just so we can last a little longer out on our travels.
With that in mind. Add puddle of water to every area and every level for said area. Just enough to lengthen our journey but not enough to make our food obsolete
