So yeah I ended up discovering that if you get the chance to be between froggers second return of his attack while in section with the double doors that require you to pull a lever, it clips through... Good to know now that run ended. It wasn't a good run at least...

It's froger.

every entity will go there, not only froger

I had this happen before in the ridge. As I got to the door, I heard froger, but thought I would be fine. Then just as the door locked, he clips through and killed me. Wasn't super happy since it was a decent run as well.

mods, delete this shit ^^^
