This is an amazing game, one of the best I've played (version Ch4.0-0.3).
1. The girls are beautiful, varied and have different and well established personalities.
Some of the girls are very beautiful, especially Juno (milf) and Lia (girl).
The MC's mom and sis are also beautiful and pretty: less so in the beginning of the game, but they get better during the later chapters of the game.
Other special female characters are Callista, Freya and Aphrodite (milfs).
2. The story is the best aspect of this game. It's very different from most incest games where the MC's main activity is to seduce his mom, sis and many other girls.
Here the story starts similar to that, but evolves quickly into a much more complex and fascinating story involving Olimpian godesses, a succubus, etc..
An interesting point is that the mom is not the most attractive woman in the game as it is customary in very established incest games like "Milfy City", "No More Secrets", "Life in Santa County", etc.. In my opinion that's Juno, the MC's mentor and initiator of his adventure. Also Juno's role grows to be the most important character in the game after the MC.
Also, the mom is not the ultimate "reward" for the MC, the last woman he gets in the game, which is contrary to the established pattern.
There are a number of characters that oppose the MC and his mentor Juno and the fight between these two groups makes for a captivating and gripping story.
Whereas in a "regular" game the side story is a distraction to MC's seduction of mils and girls, here the story grows to be more captivating than the seduction of various female characters.
Also, the short side story "Milf dilemma" is funny and sexy and the MC gets to fuck Linda from Milfy City, the mom from "The Visit" and another milf from yet another game.
3. In conclusion this game is quite unique among visual novels, it's one of the best I've played and I highly recommend it.
