Hi, I'm having the same issue on Windows 10 64 bit 1608 build.
I end up stuck on a tricycle in front of a closed door (the second door). This builds up by first the mime king disappearing just after the first door and you end up chasing nothing from then to the second door. After a few re-runs I found the mime stopped just after the second door - if I kept on machine gunning him (facing backwards) around the subsequent twists and turns the mime king ended up catching up, then going through me, the taking the lead again. Now the mime king reaches the second door then peels off down the alleyway to the left, still leaving me stuck in-front of the closed door.
Does anybody have a saved game just after this point they can upload to the download site so I can proceed - I am aware that I'll have your skills progression but hey?
