where you’re a tiny person exploring an intricate, hand-made world inside a world
I have come back to you as I left: a fool.
where you’re a tiny person exploring an intricate, hand-made world inside a world
another crab's treasure, which just came out, has similar vibes to these -- the world is built out of trash and sand
What immediately comes to mind is katamari, though that one is maybe more nonsensical than what you're looking for.
Also, not 3D, but the hamtaro games on GBA were GREAT at conveying this sense of scale
Supraland is a fun first person puzzle platformer/rpg where you play a tiny clay man in an intricate sandbox built by a young boy.
Very different vibes (adult, surreal, sad), but Maquette is all about exploring a hand-made world.
Ah, longing to be a Borrower.
If you're okay with being a mouse person instead of a human person, Postmouse is lovely (and free!)
