So since I’m using fnaf engine I don’t know if I have change fnas 4 more but if I do then here’s my idea where You’ll still be in the fnas 1 pizzeria but abandon but you’ll have cameras but only two cams to look through which would be the left and right hallways and if you see nightmare mario or nightmare yoshi leaving the halls you have to hide under the desk like in the original nightmare sonic and nightmare golden sonic would also be this way but with nightmare sonic would be where if you hear him running hide under the desk and wait until his gone however nightmare tails would have a completely different mechanic where he would be able to run down ether hallway if you hear his tails then hide under the desk and wait until his gone and the toymare would still go through the vent but you’ll have a flashlight to check the vent and the vent would be in front of you aka in front of the office where and desk would be and if you see the toymare then if the button next to the vent to close it and wait until his gone
