Who has ever said this is/has to be a masterpiece
It is a funny game to play and without false pretensions, unlike many of "big" and more popular games.
If it stays this way, it fits just nicely into average quality we could see in most games.
Animations are hype of horny porn-hubers. Those who usually dont need a story, dialogues etc..., yet only need animated fuck scenes repeating over and over again. So, yep, I would say, animations are overrated definitely. If you want to watch animations better watch video/movies, you have a a lot of possibilities there, including lifeselector "games".
VN porn games should be focused on the story, players choices, fine build-up and finale/rewards/sanctions..i dont see much similarities with porn-comics there.
In my book - animations could be an useful addon to a porn game/VN (definitely better than "music"), yet by no means it is something "must have".
