Physicus: Save the World with Science!

Returning from a long journey from outer space, the player receives a call for help from a professor: a meteorite has crashed into the small home planet and brought the rotation to a standstill, making one hemisphere unbearably hot and the other unbearably cold - only an impulse machine can get the planet going again. The player's task is to use the professor's notes to complete the machine and save the planet.
