Goldhunter (UK) (1987) - Amstrad CPC - Adventure, Exploration

You control a robot in a mine full of gold but also full of dangers. First, there are spirits who drain energy from your robot. But there are plenty of gas stations to refill energy. Footmines make your robot explode. Conveyor belts make robot moves hazardous. Elevators can only be moved when you are standing in them. Find the codes to open doors. You only have 20 minutes to collect all the gold pieces. Anyone who still manages to do it will receive a few bonus points.
