I have to ask, were you able to successfully save the game at any other point in time? Or was this a hard error and you weren't able to save no matter what?
I isolated the bug and removed the "konami listener", thanks for letting me know!
I'll be pushing out a new version of the game with the bugfix. If you're still looking to read further into the story and be able to save your game, feel free to download the new version! will let you know once it's out.
