While I think it's a rather creative and awesomely meta scare, it can be rather annoying. I think the simple fix could be that when the player unpauses after that certain amount of time, then the scare triggers. It's kinda unfair, especially since 106 will eventually spawn on you after a while, and kill you, so if you legitimately have to go afk, then you get punished for that, which seems like a big no-no.
Also, this feature seems to have bugged the ending screens. After the certain amount of time, it'll take away the "THE END - achievements asfaga" screen, display the "STOP HIDING" text and sound, and then play the ending dialogue again to the ending CB logo again.
It slep time bunner.
