Ahhh I love this! I can see like a full cozy game with different levels of people being ghosts and having to do ghostly things to achieve a goal. The thing I would suggest is maybe having a button showing the player what they can interact with? I struggled for a bit longer than I'm willing to admit because I didn't realize I could switch the direction of the fan. It could just be a me problem though. Great work!!! <3
ps: I also love the art.
