No-commentary playthrough:
This was a real son of a bitch to figure out. The game is like one big puzzle and keeping track of all the details would probably have been impossible had I not done an extremely deliberate exploration of the entire building while taking notes before trying an actual run. Be warned though, if you're going to try something similar yourself, that asshole clown will still hunt you down in exploration mode, despite what the menu tells you! What a dirty trick!Now... on to the factory...
