Hey! Thank you for the kind words 🙏
The premise does sort of depend on players getting distracted by things such as the bank etc, something that is more likely to happen with more players. When that isn't the case throwing some spanners (hyenas) in the works like you did is a great way to handle it.
The horse idea sounds interesting and could defo work, though I would consider how to handle a larger group of players where people may have different kinds of horses. I suppose they would have to adjust to the slowest person in the party?
