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.
