Caribdis animations are really good, and his models are great, I remember I wasn't sure I liked them at first in Once in a Lifetime, but they grew on me, I'd say it's mostly because of how he brings those animations, they're brought up slowly and then the music drops and everything becomes more intense. All that thanks to his storytelling.
Honestly, it's what I like the most about 'adult VN games', stories, writing, plot, character arcs, and humor. Otherwise it's just another porn scene that you simply fap to and don't remember afterward... there's a reason the best rated games on here have great storyline, sound character arcs, of course great animations, but when an adult game can make me laugh, it gains a lot of points.
Like Eternum. (and it's awkward starings, damn)
