I adore this video game so much! It was very well done, and the cleaning was very satisfying. I personally, as someone who LOVES jumpscares (unique, I know) I really enjoyed the way they were done.
SPOILERS FROM HERE ON OUT. IF YOU HAVEN'T PLAYED THE GAME YET PLEASE DO IT'S REALLY SHORT AND WELL WORTH YOUR TIME
The twist at the end got me. The way that you have a sort of...sense of ease built up over time, even though you "KNOW" a jumpscare is coming, that it's a horror game, so many windows of relaxing cleaning and even seeing the residents inside doing things regular people might do, like reading books or watching tv. It leads you to not suspect anything of the residents DIRECTLY, and even when something does end up happening, you think its a murderer rather than the actual people inside. I also personally really enjoy the art-style, the simplicity of it, and how short it is. I like shorter games, especially horror ones, and this one was about the perfect length of time for me. I look forward to seeing where you go in future with these if you plan on making more video games, horror or not, you have a lot of talent and i'm sure that it will be lovely. The only thing that confused me a bit story-wise, is the fact that the window cleaner protag seemed more concerned and perturbed somehow by having dropped their truck's key rather than witnessing what for all they know could have been a murder or something of the sort, with clear vibes of something wrong that did break my immersion a little bit, but it honestly is a small thing, and it certainly seems that the small bit of story/premise you get is otherwise pretty good. They're just like any other typical horror protag I suppose.
