The stage design itself, as well as the reason for Youki being shrunken down, have gone totally without discussion at this point in time, ahaha. I've assumed it's shrinking magic of some kind based on how Dran has magic for making things grow, based on the boss slime's dialogue and Dran's own battle. "Size changing magic" seems to exist in the setting. If I had to take a guess, the stage may be a combination of outdoors and indoors, as there's grass that Youki can hide in, but also vases she can drop on enemies. Or at least, the latter was in the first look at the stage...along with a rake for enemies to step on. I wonder if he's really going to implement that...
I asked about game over scenes, and it turned out that the mandragora normally spits out Youki's panties, it's independent on being a game over. It looks kinda weird like that, but that's how it is, there isn't anything special for game overs at this point in time. I did suggest doing something special for game overs, but also said that the important thing is that something is done to make it clear that the monster girl enjoyed eating Youki. I'll be a little more detailed with that next time I talk to Nana, as I did have something in particular in mind for the harpy when I said this. I've seen videos of birds kinda shaking their whole body after swallowing something like it feels really good, I want that kind of impression with the harpy, where she feels so good having Youki inside her stomach that she does something like that, or maybe flaps her wings happily, basically anything to express "mm, that was delicious!". Anyway, regarding doing anything special for game overs, Nana said that if there's enough time after making everything, he'll consider ideas for game over scenes. I think that this is unlikely due to the intended release date of August, there're already concerns about going into September, but Nana said on Twitter that he'll try not to worry about it and concentrate on making the most enjoyable game he can. I'll discuss this idea with him again when the timing's good.
Forgot to mention this in the prior post, but Youki's H gauge now accumulates while inside of mandragora's stomach, in addition to her HP gauge depleting. No word on whether or not the H gauge filling up will lead to the same result as her HP going down to 0. I'm inclined to think so, but there are some potential ideas to discuss with that kind of system...
