Congrats on finishing your first game!
The art is amazing, the ghosts look great and the night / day switch looks cool too
Even though it's not finished, I can see you had a good idea, if was a bit difficult but I managed to find the pink thing for the ghost, good job on that y-sorting, gives a nice level of polishing to the game.
Some feedback: Would have loved some music and sound effects, a start menu, some visual queues for example showing an E button when approaching a ghost, I'm sure you couldn't make those because of time but just some little details. Game has a lot of potential so keep going!
