I'm starting to think Neyjour's got in in for me...

As a non-gamer, I can't really speak as to whether the webs are unnecessary. What I can say is that they look great, though perhaps it does give a clue that there's something nasty nearby.

My idea, when I started reading your comments about the web, was that Mamma Critter crawled up the wall, spun a web and laid eggs on it to keep them up off the ground where it was safer. After they hatched, they'd fall through, down onto the mushrooms where they'd get nourishment to grow.

Either way, it's ghastly!!
