Edit--Updated to reflect progress for 0.16.
I try to be as honest as I could, when shifting through the smut.
The game for once, when I first booted it up back during the 0.5/6 days had hit me that it felt like a game, rather than another engine shouldering h-material. Not as much h-material back then, but now it's sufficient enough to present itself as solid material down to the edge of the current version, especially the waitress route and other moments in it's story.
So, the writing is fantastic. The main character has a personality, she's bubbly, heroic, and apt for a world cursed by a corruption-like apocalypse. With the many events that test her corruption, they make sense considering her backstory and how the world had come to be (which is explained in the intro). It gives a plausible (at lease in hentai land) reason as to why everyone is horned out their minds, and how the MC has both the corruption route, and the route of staying as a hero after the hentapocalypse. The writing naturally steers towards territory to test the heroine on her morals, which leads to very well written corruption scenarios and plausible future features the MC can end up in.
Some features are corruption-based exhibitionism, varying levels of sluttery when presented sexy scenarios depending on your choices, art that gets better and better, and a rather well presented story. As mentioned, a lot of this is just so well written which gives a lot of substance to the corruption taking place if you want your choices to lead as such.
On the art, it's well done. Previously it was kind of weak, only giving a glimpse as to what could be in terms of visuals, but with the recent change of artist in relation to the main CG's taking place, both in the casual regard of getting groped and major sex scenes, it's fantastic. It gives the MC a real sexy vibe on her dipping deeper on the corruption, rather than the disjointed art some games can have in relation to what the text is trying to show. I mean, the main banner for the game on this page is just fantastic when you pair it with the writing and the MC's thoughts once you play it.
Minus the porn, as said, I thought this was really the first game I played in the pornmarket when it came to games. Instead of the typical chore of slogging through the gameplay of an RPGM, here, the turn-based combat is really nice, you see it all pan out in in a grid based manner, with the MC having her own superpowers being demonstrated nicely, and having group based combat really make sense. It reminds me of Disgaea without the grind or geometry. That's another thing, no grind at all in this game that I've found which is a major plus. So the gameplay is fun, instead of being a chore for more CG's, and not too difficult in itself.

Previously I had stated that the content within the main hub-town wasn't as developed as the main quest of the game. Now since my initial review, Anduo Games has added not only a waitress route with a lot of nice lewd, but to top off what you do in the bar is further expanded at the freeuse stalls. Just, truly magnificent. I hate to state such things for a game in development, as any turn can severely impact progress especially in this industry, but I am truly proud of what this game is going towards in comparison to the vast majority of others within this site. Soon too, they're going to add more freeuse content while walking around town, much like noxian nights (if anything I believe they took their cues from that), great progress so far.
All n' all though, 5 stars considering that the professional quality of this game shows that you can have a well developed western game in this market, rather than having to bank on Japan making the real gems, or the western markets scrambling for assets and abusing RPGM. Hoping that it continues on the good route.
