Very charming game! It felt pretty relaxing to do all the chores (maybe it's the "checking boxes on a list" effect?). Watching this little ghost living his own normal life as the same time as our character, in the same environment, but at the same separate from us, really added a second layer to both gameplay and atmosphere (I don't really know how to describe other than it felt pretty nice, a bit otherwordly and again, relaxing).
I did feel like the camera was sometimes behaving a bit weirdly because of walls and ceiling, but nothing that really hindered gameplay. I wouldn't have minded discovering a few more things about the ghost, or maybe having an ending that wrapped things up a bit more, but it would probably have been hard to do in 1 week.
Overall, pretty fun and charming, fits the theme well, great job!
