This one in spooky game from years a couple years ago.

I remember that the mc was going to some sort of haunted house where there were like, 2 ghost girls, a pirate themed girl, and a slime girl.

One of the ghosts was cat themed and was obsessed with cardboard boxes.

I have no clue if it made it out of development, but I remember all the time seeing posts about it from the solo indie dev, who was also the main artist.
