sounds good ty.
Also you could add someone in vents like balloon girl that way u cant really cheese the game. Power meter probably should be added, maybe when the power goes out the animatronics become more sinister (lewdier) You already have the fuse box and maybe add a crank to add Manuel power back.
Future content could always add a 2nd floor (can be basement for more scarier or adding and upstairs) This could easily be fore adding more quest items to make it harder.
These are all suggestions.
