This game had a lot of heart. Did you make all the visuals yourself?
Most of the feedback involves noting technical issues that I'm sure you are aware of. The camera has a lot of jank and it's almost impossible to control on the second floor. I'd recommend looking into CineMachine and it's CameraCollider components. It will solve all of those problems.
Everything here looks like it was authored originally. The animations and models all mesh together well. Also the screenshots for the game over screen and winning screen were a nice touch,
From a UX standpoint, there's no reason to have a sprint button since the ghost is faster than the walk speed. I would remove it outright since it's not utilized.
It's impressive that you went for a third person action game for your first entry! There is a lot of good work here.
