You should watch ad to earn money, which needed for things like defending against some enemies and buying energy. Also having some amount of money is a mandatory to complete a night (If you have less that, lets say, 5 coins when night ends, you get a game over and you should play this night again)

Everything still in very-very early stage of development, and I still have nobody who can draw well so its kinda ugly. Central cube is door (like in Fnaf 2), and one with animation is TV with ads
