Hello I want do a speedrun of granny but can you tell me. Can I do any glitch?

There is absolutely no need to glitch in this game. There are no useful ones, anyway.

There is a glitch that can block granny in the first room in front of the bed

Not worth it, though as it can not work most of the time.

Okay

I think that when you get bedglitch it can save a bit of time because you do not need to change your route.

Nice necropost
