Here's something new in the works: alchemy system.

You'll be able to craft potions out of ingredients you can find in the world. These ingredients, once harvested, will respawn in game time after X amounts of days passed.

It works hand-in-hand with the day/night cycle. There's an internal counter that counts the days passed in-game, and then for every ingredient picked, an integer variable is set for that item with the day that the item was picked. Then, the day/night system will do the rest of the guess work to know when to respawn the item.

In this example, the flower respawns every 4 days.

The UI is lacking some sound effects and neat particles, but it will be added in due time!

Next in line is adding potions that add consumable effects for a time (think raising attack power for X time or double jump for 10 seconds). 

Last in the roadmap is the parry system, and being able to inflict negative status on enemies as well (it would be cool to bleed an enemy with an axe, or poison them).

Anyway, here's the video showcasing alchemy. Enjoy :-)
