During each Day, there is no time limit. However, the Day immediately ends if the Player is caught by Granny, is bitten by the Spider, falls through the hole in the Attic or explodes themselves with the Gasoline Can.
This is the very first Day at the start of the game. No doors have been locked (excluding the Door between the Dining Room and the Backyard, and the door between the Jail Cell and the Baby Room; as these Doors are always locked and only Granny can open them). The Player does not appear to be injured at all, despite the fact that the Player was most likely hit by Granny with her bat and was dragged into the Starting Bedroom before the events of the game (as seen in the PC version).
If the Player gets to Day 2, they will find that they wake up with a slight limp.
The Player's limp has gotten more noticeable. The Door connecting the Main Room and Bedroom 2 is now locked in its place and will stay locked through all future days until Granny is lured into unlocking it.
This is the last day you have to escape unless you unlock the Bonus Day. Otherwise, if you get caught, you will get a Game Over.
