Great game, really, the idea, the theme, and I love medieval kind games.
Do you nitice that when you are near a wall and rotate your player, you look the outside of that wall?, I really recomend you, the use of Cinemachine virtual cammeras that let you limit the field of visión of your third person player, viewing just the inside of the building where you are when you rotate your player.
The idea is that you layer your walls with a customized layer, for example, a "Wall " layer, then select your Cinemachine virtual cammera and the Cinemachien virtual component, you need to open the Body section and search there the Obstacle title, just down from that title, there is an option named Cammera collision filter, open the combo field next to the option name, and select your new "Wall" layer, prove now your third person cammer near that wall and buala, your cammera don´t look anymore the wall outside.
Good luck to your Project, I think it is a great one to win the contest.
