BORROWERS || Original characters and game concepts

Will you cause chaos from the shadows, or will you take on the role of family guardian and help solve each human's problems?

The BORROWERS are character avatars in a game that I would love to make reality someday, where the player needs to sneak around a house newly bought and now overrun by a human family. It would be a 3D platformer with stealth elements involved, with magic to help shroud the player in darkness as they move between shadows around the home, collecting food and supplies for themself to bring back to their homebase, hidden away in the attic, far from the family's reach.
