Hey, Matt.
Because of a series of very unfortunate events, the version of the game submitted has a fatal bug, the one which you encountered, and you can't progress further in it.
Since the jam, I've fixed the bug. If you want, I can send you a build to play personally through a file-sharing medium.
Sadly, the bug cannot be dodged in this build, and I don't think this submission has any hope.
:( I'm really sorry, man.
