The pixel art is glorious. I really liked the art style. The music was used very well. Flipping between calm and horrifying. It's very short, but I was genuinely surprised at the twist. I thought I was just cleaning up muddy footprints!
Recommendations:
- Longer.
- It's best not to capture the cursor if the game doesn't use the mouse.
- Add more to the game play. Maybe you have to avoid guests seeing you doing the bad thing and so have to pick the moment carefully. Try to have some kind of lose state.
