I liked that you could ride any horse, so I stole many horses and scattered them across the map. It's a bit bare bones at the moment but there's so much potential to give the game some world building elements to it ! There's a little nook in one of the mountains that's really a dead end, there could be a skull there, it could be a deceased relative of the prince. Maybe one of the houses was ransacked and burned down, did the royal guards do it ? Is the emperor a kind and just ruler and would you still save him ? There's a lot of space here to work with to build a story and give the players an incentive to go exploring, but what you have here is a solid groundwork to build good stuff on !
