I really liked this, great job! The atmosphere is good and I love this type of rpgs where you have to interact with the enemies in other ways. The graphics and aesthetic of the environments and ghosts are great, but the UI and text size needs some work (I know the pain of trying to make UI work in Unity lol)
I made a similar rpg concept in godot but put too much focus in the combat mechanics and couldn't finish the story nor environments... If I had simplified the scope I could have made a more complete game so I took notes from your entry! (I also wanted to add negociation with enemys in battle but had to scrap it)
