This week, your aim is to allow the player to take control of the random things around them.
A game which feels random, but is in fact mostly planned. A game which relies upon the user's input to decide upon the randomness, and where the amount of randomness can be controlled by the user, but only once the user works out how the randomness is being generated. Perhaps the mouse's position will decide how flat things are. Or a certain key combination will alternate the oncoming random route.
