Err is a prototype maintenance robot designed to keep this facility powered ON but there's a flaw in Err's design which requires Err to be rewound in order to work. 

You have to rewind Err to keep it functional and use Err's throwing ability to throw batteries at the power stations to keep the facility running.

There are a total of 6 sectors to power up. Good  luck!


  • WASD/Arrows: Movement
  • Left Mouse Button:  Throw/Recall Battery
  • ESC: Open/Close Pause Menu


  • Designer & Programmer: Nelson Laracuente
