Really fun game and super cool to experience things from a Tavern Keeper's perspective. I definitely agree with the other feedback post that it would be cool to be able to spend gold on things other than quests, like upgrades to the Tavern Keeper or the tavern itself.
One thing that might really add to the "Tavern Keeper" experience is being able to take drinks to tables as a way of getting a small amount of income. This also comes naturally from the way the camera is positioned. Obviously this is more of a subjective design choice depending on what you want your game to be. Really fun and can't wait to see more :)
