Just gave your game a go, awesome job!
I love the art style and the design for all the different characters and their custom animations. It must have taken a long time to make those so good work.
I ran into a crash when I accidentally pushed one of the book boxes into the shelf in the library. It froze up the game and I had to quit. I believe if you check the Skip if Cannot Move box in the event's movement, it will stop the game freezing if you try pushing it onto an unpassable tile like a wall or shelf.
That said I thought the game was awesome, the music fits the theme well and it gave off some creepy and mysterious vibes for sure.
Overall, good job I had fun playing :)
