"While running game code:

IOError: Couldn't find file 'audio/voice/chiaki/ch01.oog'.""

Will no longer be a problem.

I am so terribly sorry about the inconvenience, I should have done a final check before uploading this, as this problem occurred by the very last change I programmed. There should hopefully be no more bugs/errors this severe, but if there are, please let me know and I'll happily fix it. Good thing this is marked as early access.
