This game takes place in the memories of an ordinary man.
It's a third-person action-adventure ball game.

You control the ball,
and explore various aspects of the man's past:
his childhood park, his school, his first apartment, his part-time and full-time workplace...
Find the meaning to his life by experiencing his life events:
leaving his family, loneliness, society and interpersonal relationships.

The game is separated into action stages and adventure stages.
It also contains both puzzle and horror elements.
Some stages imitate reality, others are more nightmarish...
