Excuse me if I am wrong, but I'm 90% sure I saw somewhere characters on horses, like the riding poses in "Mana Seeds" style. Was it yours and can I buy them somewhere?
You are correct! The character sprite with horse-riding animations is my "Farmer Sprite System" and you can find it here: https://seliel-the-shaper.itch.io/farmer-base
I will (hopefully) be publishing the horse itself in a few months.
