You play as a gremlin and your part to play is you steal items from people like, socks, you tangle up Headphone cables, you slam doors behind people and you hide keys around peoples houses. You do all of these things to be a inconvenience, To steal socks you hide in the tumble dryer and wait for people to put the wash on and you steal the left sock from the pile. To tangle up the headphone you shrink to a tiny size and you hop into the pocket of your subject you are inconveniencing, you tangle up the cables and quickly make you escape. To slam door behind people you have to hide behind doors and wait for your subject to go through the door, and to hide keys around peoples houses you steal the keys and put them in a place where it will take the long to find the keys.
You do all of this to be an inconvenience and you find pleasure in toiling with peoples lives.
