The Last Engineer

You are The Last Engineer, but not because there's no one else, but because your grades were so bad that you ended up cleaning spaceships for a living as no one would hire you as an engineer. 

One day while you  are cleaning a spaceship, you dropped coffee over the commands table and the spaceship lifted off. Communications are broken and the ship is flying uncontrollably directly to an abandoned planet. luckily, you remember some of the things you learned studying and the systems are simple enough for you to repair with the help of what is left of the ships AI.

Your mission is to make it to the planet landing the ship safely not dying in the way. Also you'll have to repair and use what is left of the space station in the planet. But it won't be easy, resources are as limited as your knowledge, you'll have to figure out how to get back to your awful job as a janitor and pray so that you don't get fired for dropping coffee in a ship you were supposed to clean.
