This one is just terrible. The story is no bad, it's worse. Characters have no interest in them, the writing is bad and has translation problems, events are so predictable and utterly uninteresting it almost hurts, etc. Add a non-existant gameplay and that is that, worse than most japanese games.
Art should be the salvation of this but it is not. Art begins at a mediocre level and quickly dips into abysmal levels, with low resolution and bad execution. Music is terrible as well, and there is no real voice acting outside random sex moans, unlike other japanese games. But, like those, this one has no animations.
So, all in all, terrible all the way around.
