Here are some of my ideas for the game. Please consider them.
Jewels
Blacksmith hoagan says, "Im trying to level up my smithing. I'll do it for free if you have the juice" which leads us to believe that juice is more of an element than a currency. So what if there was a currency? Jewels could be dropped by enemy and earned in other ways. You could spend them at the Old mans house and get some good weapons. Or you could trade them for juice somewhere else.
Time scale weapons and spells.
There should be weapons and spells that adjust the time scale in some way. Maybe it could be a sword or hammer that slows down time when you swing it, or this could happen with all weapons when you defeat an elite monster. There could also be a spell that slows time and boosts the players speed, and also maybe change the colors on screen.
Day and night cycles.
This would be cool, although I don't know how it would work with the fog. Certain enemies could only appear during the night and some during the day. Night time enemies would be more difficult than daytime enemies. You could spend juice, (Or jewels I'm just saying) at an inn to skip to day time.
Treasure caches
You could get a scroll or something from the old man or mr.fox that would lead you to a treasure chest. Inside would be some items and another scroll that you could return for juice or jewels.
Custom items
If an item is rare enough, it should be given a name, just like elite monsters.
