Recently, the author of the YouTube channel Kilroy Was Here talked about his adventures in Hollow Knight Silksong. He managed to do a softlock.
He did not release the Bell Beast; instead, he went the other way — he went to the West. Then he farmed resources to purchase the key and opened the locked door.
Soon a section appears where, as it may seem to an ordinary player, it is impossible to pass without a dash, but there is a way out — it is necessary to kill Hornet. After resurrection, a cocoon spawns, which can be used to get to the desired platform.
Then Kilroy Was Here went to the point of getting into prison and faced a problem — since the Bell Beast is still imprisoned, Hornet cannot escape.
