Figure will be seen only at door 199 or 200 as when he jumped down at 00:43, you can hear the Unhinged II soundtrack play, which only played at door 100 Seek chase will probably replace door 50, or even that screech worm boss
As someone who’s exited for the mines, I can 100% agree that some of the sounds are leaked without music, and this would be what the gameplay sounds like. 👍
