Two engineers work on a small planet somewhere in space. The planet has a diameter of about 100 meters and a very weak gravity.
The local sun always illuminates the same side of the planet. Your base is built on the day side. All work on the dark side of the planet has since ceased.
Your colleague left the base without warning and does not get in touch. You go to the surface of the planet to give him a suggestion.
Controls: WASD – move, space – jump, F – flashlight, E – interact.
