Inspired by the dual screen of the Nintendo DS, What Linus Bruckman Sees When His Eyes Are Closed is an adventure where you play two games simultaneously, real-time, and in split-screen. In Kami, you guide the spirit of a female samurai, killed in a village raid. To save her people, you must free the fallen god Izanami, trapped deep inside the same caverns. In DocMcVonSpaceBurger, you are the cartoony alien Junior, only wearing undies. You have to help your father who gambled all his money. The only way to avoid bankruptcy is to restore the order system of the DocMcVonSpaceBurger fast food empire.
The game itself consists of a single screen, with one, very thorough puzzle. The twist is that any action you take in one game is mirrored in the other. In the first run, Kami is completely in Japanese and thus impossible to solve if you haven't mastered the language. When you complete the DocMcVonSpaceBurger puzzle, however, the Japanese text is translated and you can start a second run. Each of the two puzzles (top part and bottom part) can be solved individually, but based on the outcome (fail both, solve one, solve both), there are different endings.
Even though all actions are mirrored, there are a few tricks involving switches, colours, and different axes granting a little amount of control over the different effects. In Kami, you need to rearrange the fragments of a story based on deceit. In DocMcVonSpaceBurger, the main challenge is to find out the customers' needs and provide the right capsules. Both games have distinctly different art: the top game has a stylish oriental look, while the fast food empire is very cartoony.
If you manage to crack both puzzles simultaneously, you are given a code to add your name to the hall of completion on the developer's website.
The duality of the gameplay is reflected in the announcement of the game. Creator Vincent Twelve advertised the two games separately in various forums, Kami using the alias Sanou, and DocMcVonSpaceBurger with the nickname RightMind. The story for both games was explained, along with some screenshots. Because of the contrasting graphical style, it was impossible to link the two games. When the final game was officially released, the creator announced the two developers had "teamed up", and had woven their games together, only to reveal the real concept afterwards.
