Rime (video game)
As the boy climbs the tower, he comes to additional areas, each individually represents the five stages of grief. Eventually reaching the top of the tower and exploring the area representing acceptance, the boy is forced to let the fox go as it disperses before him. He returns to the central tower and finds that he is now inverted within it, and climbs back through it, eventually reaching the "top", the initial island.
