you, and the animatronics have a dice 1 to 20 in every action

example: if the you want to close the door, you first throw the dice

if it's a 1, the door breaks completely and breaking your energy completely

if it's a 20, the door will not only close completely, but also barely take any energy

(and possibly, if the final boss is an amalgamation or some kind of thing, they throw the dice to either be super powerful and strong, or just break completely)
