I like your animation.
Tentacle's movement, x-ray, Erisia's various sex position are all great but especially blob plant's zoomed-in lens was truly impressive.
However, the changed art looks a bit strange to me.
That's because when you depicted Erisia's nose, her face ended up looking elongated.
If you want to depict Elysia's face in detail, you should aim to portray her more beautifully. Otherwise, it might be better to boldly omit the nose.
And what I felt while watching the menu animation was that the description of eyelashes greatly changed Ericia's impression.
I think it would be better to make the eyelashes appear thicker.
Bug report: Erisia can move while using an item if you enter and then exit the in-game menu.
