Nintendo DS is a game that is being played at the local store. It is a puzzle game that is set in the future where you are one of a group of astronauts who have found a new planet that has a lack of gravity. You are able to use your DS's camera to take pictures of the environment around you. Once you are done, you must send back the passengers of the planet to before the game began. The game is over when you get to the next step, but you are not done yet. You must send the players back in time and allow them to fix the mistake that they made. If you complete the game, you are given a prize like a new DS game camera or a discount on the next game that the store offers.
