Well, I want to tell you my idea. I personally think that there is not much more to add to the house. I guess that part is completed. So, in the next update, they should add Multiplayer. For 2 people. One is the Player and the other one is Granny. The player who controls Granny will hear every noise made and will have the option to put traps whenever and wherever they want (as the default Granny). The Player will have the same mechanics. What do you think?
There are a few things to keep in mind- Maintaining servers Possible exploits
What I mean by exploits is that if the player behind Granny can put down traps at will, you'd have traps up the wazoo. That can be stopped with a cool-down. Granny could also camp near vital objects, but that can be solved, with considerable labor, by giving more than one vital location for another. That basically means the amount of object are doubled... That wouldn't be easy. But there's probably other ways.
I would like another character that can kill the Player. Also, something has to be done about starting the car. More easter eggs because the game explains too little about the backstory. Mode where Granny is gone. More uses for items, don't quite like the items that only have one use, too little creativity. More locks or able to escape with car. More items to help with advanced escaping.
