Yeah it’s different.

Spring Freddy will appear in either hallway camera and will stand there until he moves into the doorway (but will not be visible in the doorway). Closing the door will have him jumpscare you, so putting the mask on. Since he is a bit of an older model he is a lot less likely to recognize you… or at least for a moment.

[PROTIP: It takes (50 - AI) seconds to go from hallway to office when he decides to move from the hallway camera (which is every (75 - AI) seconds. He also takes 10 seconds to kill you. As long as your mask is on by the time the 10 second killtimer passes, he will not kill you.]

Changed just for balancing.
