Very spooky, I liked it! Each of the kids had interesting dialog, and the atmosphere was pretty spooky. When the thunder started playing on repeat, I had to turn down the volume because I was expecting a jumpscare or something haha!
Overall very good! If you were to continue this project, I'd consider adding more things around the house for more environmental storytelling. It'd give the player something to do while waiting for the next kid to ring the doorbell. It looks like you already had that in mind, with the old man's food laying around the house.
