Definitely a weird entry, that had an interesting game loop I've got to say. Although I don't quite see where the theme comes into the concept, or the gameplay to be honest. Especially since the ratings page confirms that the ghosts are real. Which I honestly assumed they wouldn't be and that would be the point of the game and the incorporation of the theme.
ignoring that though it does have a decent gameplay loop with a few ways for the ghosts to utterly get you whenever you mess up a little bit, although it does end up being relatively easy as long as you don't be like me and forget the interact button. Ignoring that though, there's never really a significant amount of time needed for any one task, besides the lights task which lead stop the tasks almost never piling up unless you mess up or let them.
I feel like if maybe the tasks piled up faster it would add a bit more to what seems to be a goal for fast paced gameplay, kinda similar to Among Us's Sabotages etc.. If that is the goal then I think leaning into it could be more interesting, cause at the moment there were a lot of times just waiting for the tasks in the same spot to show up. So it could add a little mix in there to have "emergency" similar to Among Us (only using this as a reference due to the similarities UI saw in controls, style and gameplay.
Overall though a decent setup mechanics wise for a task handling style game and some very nice written lines for the ghosts, added quite a bit to the humor of the game for me personally just seeing them in the corner I do feel like some sort of extra visual cue for them would be interesting. to make them seem more like they are there. Not sure what you'd go with though to be honest, theres a lot of approaches.
