The artstyle is pretty neat! I really like the color choices here: the warm hues reflect the sundown/autumn setting while the moderate-to-high saturation and value of some colors still make it Halloween-themed, on top of the shapes used for the background and the house guy.
I think the audio mixing needs some work though; the house man's voice feels a bit overshadowed by the background music and the sound effects. It feels very noticeable around the 00:45 mark--I couldn't understand a couple words he said at the end of his sentence.
