The world is going crazy! Humans improved their technology without realizing how they spoil nature, cutting down trees, oblivious to the fact that the level of oxygen in the atmosphere is falling. It gets to a point where people cannot breathe anymore. One man has grown a lot of trees in his backyard, and begins selling the oxygen they produce.

One persistent guy really wanted to know where all the world's plants had gone, and sent out a robot programmed to detect even a single grain of the wood. Direct it not unlike you did Mario back in the day...
