Im probably not the only one that noticed the janitor is faster than quentin. When I play back to school, I actually stress because of how fast he is. Its not like the Peterson boss where he's the flash, but its fast enough where I start stressing as he gets closer. I think you should speed up some of the AI in the base game as well so this stress of "oh my goodness he's gonna catch me" is present all the time.

I found this annoying at first but I grown to prefer it in a way.
