Accelerated Assistant

The physicists at Extra Vigoruous and Immensly Large - Accelerator had organized a Halloween party. "Spooky action nearby" they had called it - whatever that was supposed to mean. The management said it was to improve social interactions and mood among the staff because the past five failed experiments had taken a toll.

They hadn't invited the janitor though.

Maybe not too surprising, but what was truely strange was that all the scientists were gone. No matter the hour or day, you had never seen the facility deserted. Not until today, and you've cleaned this facility and similar for at least fourty years now.

WASD and action keys E and Q.

There's no running, you leave that to the next generation, and the one after that one.
