Happy you enjoyed it! One of the things you mentioned in the comment does do something actually, so you might try to get a better score! :) But y'know, there's only so much animation one can do in 10 days, unfortunately. You can exit with alt+f4, but yeah, I was mostly expecting people to play it in-browser, so I didn't implement any other ways.
And the whole game was actually inspired by this comic: First Haunting by Feel Afraid! :D
