I love the way you used the theme in multiple ways. That is so cool! I really strive to make a game with a cohesive story like this one day! The tutorial was also handled really well.
I thought that the walking animation on the character was a little wonky. A sprint button would also be cool. For the controls, I think WASD for movement and e for interaction might have been more intuitive, and tab could be map.
I hit a couple of bugs where the character was stuck in a walk cycle during a message, and I think I was moving the ghost's shadow during another. But the ghost was not appearing.
The game has a lot of polish, and the art is all great! Music was making me feel chilled out. I think getting the soda and having the drink animation was a really nice touch.
Congrats on a great entry!
