A really cool open-world game. The overworld and openness remind more of Mount and Blade. Being a courier isn't often a subject of a game but this one proves that it's a fun concept to play with. I would say rather than a combat system a morality or espionage one would be a bit more fun, choosing if you want to give the person a letter or using info from a letter to backstab the senders would be fun to explore. Either way, great work! Keep it up!
