These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
White Face's quotes look to indicate that it's just as scared as you are, but considering he's the one chasing you, it's possible he's just saying stuff to mock you.
Breather Level: The dormitories seem like this at first, since they're brightly lit so White Face can't hide in the shadows anymore. This is also a breather in the fact that this level occurs immediately after one of the most significant scares from White Face so far.
Nightmare Retardant: One method to not be scared of White Face/this game anymore is to imagine that White Face is actually Jack Skellington's floating disembodied head. Jack or "White Face" chases and annoys the player because scaring people is simply part of Halloweentown's culture!
One thing White Face is implied to be is a malevolent computer virus. Just delete the game afterward and run your anti-virus software. Problem solved!
A lot of the game's scariness is leeched away if you know how it works. It also assumes you're running a Windows and many of the extraneous files don't appear if you're running a Mac or—god forbid—some Linux distro.
That One Level: It's easy to get stuck in the parking lot due to the fact you're more likely going to be following the arrows, and it doesn't tell you to enter a door that you passed by and will sometimes pass by several times (and there's no hint that that door remains locked unless you've run over every single arrow). Also White Face will be pursuing you this whole time with that horrible loudening static sound. And if it catches you, you must complete this section again from the start.
The Woobie: Some of what White Face says makes it seem downright lonely, albeit mischievous.
