Here i will explain better how the game works, so if you have questions you can look here!
The game is subdivided in 5 days, the first 4 days you will do first the day shift, where you can use ONLY the exit cameras, and you have to count the item needs.

The day shift go from 6 am to 12 pm

Then you start the night shift

The night shift go from 10 pm of night to 4 am. (6 minutes)

Here you can watch the restaurant telecams and protect yourself from animstronics attacks. Every night on the first 3 days a new animatronic will add to the night. On the 5th night there are all the animatronics. The 4th night is similar to the 3rd but with higher AIs. After you beat the first 5 days you will unloack 2/3 stars on the title screen. The the extra ones are certificate endings that you can unlock by doing determinated things during the 5 days. You can make a new game without delete endings unlocked by press new game on the title screen. There are also some stars that you can unlock by complete determinated custom night settings. There is also the endless mode, you unlock it after beat the 5 days. This mode is a loop of nights. You do nights every time with random AIs. The mode ends when you do a gameover. If you win you will be in a screen that shows the AIs of the night you just beated and what night you reached. For now all! Ask me more if you need or want!
