I've found a couple of interesting things about the catacombs. Might be already known, but I didn't know about them. I've made a weird catacombs video showing both cases.

The first thing is, it's possible to get 7 exits. I thought you could only get either 6 or 8 because the number of right exits goes down when you get a wrong one. No idea how I got 7, although I've been able to randomly reproduce it. Would have loved not to first find out about it when I was 16 seconds ahead of my best pace ever, though :D. Does anybody know why? My best guess is that I entered the first exit too quickly, thinking I'd go back to the beginning if it was the wrong one.

The second thing is that it's possible for Guybrush to get stuck, being unable to progress or go back. Luckily, Guybrush can get free by using the head. Would have loved not to first find out about it when I was 3 seconds ahead of the pace of the previously mentioned run, though :D.
