Returning from a long journey through outer space, the player receives a call for help from a professor. A meteorite has crashed into the small home planet and brought its rotation to a standstill.

As a result, one hemisphere has become unbearably hot while the other has become unbearably cold. The only way to set things right is to get the planet moving again.

The player must use the professor’s notes to complete an impulse machine and save the planet.
