You've Got a Stew Going!
Your friend has invited you over for stew. He has not bothered to procure most of the ingredients.
The premise: you're a rat trying to gather ingredients for a stew, since your friend has put together the broth but is too lazy to assemble anything else.
In gameplay, this is essentially a treasure hunt for food items, but the tiny, ratly world is entertainingly realized, complete with suggestions of internal rodent politics and their attitudes towards the world of humans. The narration breaks the fourth wall quite a few times, sometimes to give the player direct advice about how to play, sometimes just for amusement's sake.
