Thanks for checking out Clean Spirit!
It's easy to run Clean Spirit for a move-in experience! You'll want to make sure the group has a good understanding of the location they're moving into, but ensuring group goals are move-in based instead of focused on cleaning will help. Players should focus on setting rooms up during play, describing how they are organizing items and furniture as a group. Many of the moves on the character sheet are designed with unpacking in mind, so as players go through boxes or suitcases of items, they can pull stuff out to gain motivation and make progress. I think you'll see what i mean when you review the way players make progress in the "start" section.
Hope this helps!
