There is only one part of the Ferace's script that never got translated into Japanese. Which is Ferace's musical number that was used in the trailer. Did you know, you can actually play through this trailer yourself if you pause the game, open the exit menu and select the credits option?
There is another song that happens at the end of the package (the end of episode 2). This one isn't in the format of a musical number, but more like a Japanese Anime ED theme (Bonus points that it's written and sung by an actual native Japanese person, Naoya Sakamata).
As you know, I don't like making non-playable segments, sooo even the credits are playable segments in a Sayuri Artsy production. I also just felt like it was a nice space to try to make a completely different kind of gameplay. Their designed to be unfailable technically. But I was hoping that players might try to make it a personal challenge to try and complete the songs without being force warped. There wasn't really any place in the story to have these auto-scrolling types of levels, since this is a puzzle game first. And I intend to have it to such that every single package ends off with a unique credits roll map.
