Okay, ACTUALLY last thing (maybe?):
So I beat Wieduch, and left with the ghost. I went back to City of Cables, because I wasn't really sure where to go. Is this the end of the demo or is there something more to do? Either way, I found another glitch. If you talk to the mustache guy in the cabin, he'll give you the gun again. So now I have both the Lady's Friend and the ghost gun. This allowed me to figure out when the misfire glitch happens. If you aim too low while walking or running (and by low I mean directly in front of you), and shoot the gun, it misfires. What's weird is this isn't entirely consistent, if I shoot close to the character then it won't always misfire.
Edit: Just found out I can grapple the other side of the bridge and now I feel stupid lol.
