All episodes are unlocked, so you can load any of them (click the book next to your save). All 120 fireflies have been collected. This is for those stuck on an episode and unable to progress due to a bug or broken script, or for those who simply want to see the ending.
Don't forget to back up your saves, as this may not work on newer versions!
