I suggest adding spider webs in dark areas such as forests, caves, huts, castles, ruins and wherever tey fit.
This would significantly enhance the game’s atmosphere and make the world feel more natural, as spider webs occur frequently in nature everywhere. I bet we all have one somewhere in our homes right now :D.
They provide important visual cues that these environments are wild, abandoned, or old, boosting overall player immersion and helping to create a believable world.
