Use the arrow keys to move, and use your mouse and clicky buttons to navigate the menus. Avoid being seen by the cameras by hiding in the shadows, and try to make sure you're not near the door when the guard turns on the hall light. If you're detected, the night guard will close the door, and you will have to go back to your starting point. Try to get in the guard's room before 6:00am!
Credits to scratchU8, he had to take this down and reupolad it as a “kiddy kid kid” thingy. (I use a remix made before it’s “kiddy kid kid” phase, change the sprites, (they were modified) and make this, so you can experience the wold feel of it.)
