Your family sends you the game that you have never beat. when you finally pass it, you have been crossed to another world where the same as the game you played. Who summoned you and can you save that world and back to your life?
Each stage of the game allows you to freely explore a limited area, and along the way you may find items such as "pick-ups," "3D clue objects," "intelligence files," and more, all of which have different functions.
Some items will affect the plot, some items have clues to solve puzzles, and some items are purely for collecting for viewing.
