Extra life system in general can probably be taken to be as a "that didn't count" kinda thing (although I like the interpretation of it being divine protection, so every death does happen and she gets resurrected each time, but that's head canon), but yeah, the general idea behind it was that Youki was being used as a living vibrator more or less. Nana was busy, but I got to ask a couple questions about the stage and progress, he confirmed that there are plans for internals for every enemy on the stage. This is mentioned in the article, but Camel is the one designing the new internals. Every sentence in this post was "x, but y" format, what is sentence variety.
