It is a 3D third person view game.

The world has come to a end. There are creatures everywhere. Inside a house, a kid is living within his/her memory. What player needs to do is to protect this kid by using the orange colour ball to erase(change) anything that is danger to the kid.

Player can not control the kid. There is no clear pattern of this kid's behavior. Player needs to watch closely over the kid at anytime and prepare a safe area in advance. There will be things/creatures hidden in places that could wake the kid up. Player needs to be careful of them.

Player can move things within the safe(orange) area. The safe(orange) area will fades out after sometime.

Sometimes player may need to drop something (make noise) in order to stop the kid from going forward. Also player may cook food, make bed for the kid. There are many things player can do to interact with the kid.

Eventually the kid will starts to questioning things around him/her. Player can choose how to answer the questions and this will leads to different endings.
