Chair blocking would make the game more tense and more experimental.
The player can setup a chair block to slow down the AI. A way for the AI to counter this would be aggressively barging the door until the chair gets busted off the handle.
Maybe also have the AI use chairs where every time the AI catches you it will block a door but unlike the AI you can’t barge down the door so you have to use the windows to get into the house and remove the chair.
