Like Clark said, the graphics feel like they belong to an older console... the Game Boy could absolutely run this, but it feels like Happy Space Cleaning Day's inspired by really really old PC games or Atari 2600 games. Sound's also pretty harsh. High notes in chiptune have to be written very carefully to avoid this...! I struggled with that a lot when I was getting into chiptune.
Imagining what this game would look like was fun though. A person walking through different apartments and inspecting all the furniture to clean things up sounds like it could be cozy (like how Power Wash Simulator got very popular off a similar idea).
Congrats on getting your game in, and happy ratings!
