Glad you like it!
It's just a 3D sprite object, I made it change its animation based on which angle the object is moving towards, and then play / paused the animation based on whether it was moving or not. It's actually super simple to do and looks really nice! If anything I would've loved to have added more 3D sprite NPCs around the map but I was already running low on time and energy so I just left it as an empty map.
