If you can make it through Three Nights at Fred, you'll be able to leave.
As the security guard of this haunted pizzeria, you have to make it through three nights, which are represented by three levels. You can choose which animatronic toy will be your enemy:
You can also choose from three levels of difficulty, so choose the one that is easiest for you. Now, here are the controls: use WASD to move, Shift to run, L to lock the cursor, F to pick up tools and open doors, and C to crouch down. Press L to open the view, then use the mouse to grab the glasses and put them on.
You can also use other tools, like the wrench to turn on power lines or the key to open doors, with the L key. Find the hidden notes in the pizzeria and collect them all to pass the levels. Be careful not to get killed by the evil animatronics that is after you and want to kill you.
Have fun and good luck!
