Making a good h-game is difficult. You need to balance good h-content with fun gameplay. This game lacked any sense of fun gameplay.
Story 2/10
You are rare treasure. So you fuck and impregnate every woman on the island and they won't stop you.
That's it. There's no more story.
Each girl has a kind of mini-corruption story but it's not that well done. You bang, they don't refuse and they get more corrupt.
Gameplay 2/10
You run around and try to fuck girls who are at different parts of the map depending on the time of day.
There's a little gameplay element in terms of earning money, buying stuff that helps you earn more money, to buy stuff that helps you impregnate girls. But it's too shallow to be of any fun.
To achieve SS rank is very grindy. You need 100 children. After like 30, you've beaten the game and pretty much all the content that's available. So 70 more is just a grind.
The end game content is just variation on CGIs. Dark skin, hair color update, and body doodles. Not worth it at all.
Art 5/10
I like the art style but the way the penis is drawn sometimes was just plain weird. Sure, draw a big weener, but don't draw it like an isosceles triangle.
The scenes were alright but not that great. Many distinct girls but not much variation CGIs. Girls have different positions depending on time of day and corruption level, but some of these scenes were basically cut and paste with different flavor text.
The writing was... there.
Overall 3/10
This game is basically a nukige. Run around and bang girls. But I also don't think it's well done.
If I ask myself, "Did I have fun?" The answer is "No, I did not."
