This is the best skin tight female corruption lesbian focused H game you'll find (although focused on a male player satisfaction, and not much romance so not much yuri or lesbian love here), and yes, for the degenerates that want to know, there is futanari content (us being it as well as Ayano) BUT, really later in the game, so in case you came for it, don't worry gallery is on 1st save...
Pros:
Yes, it does have corruption, more than 1 girl accompanies the Female Protagonist, amazing art, and voice acting, there's also sounds, while it isn't 100% machine translation, luckily you can understand a bit of the plot, but it's not really that much to get out of, to summarize it, Shion, our blonde beauty is going to rescue her fellow companions from a dungeon also, it comes with a full 100% save with all the scenes already unlocked in the gallery (first and 2nd saves so think twice before saving there), you can have "sex battles" but only with important characters, such as your companions and the end boss...
Now for the cons...
The only and big con of this game is how impossible it is to actually be cappable of moving from 1 place to the other without getting lost...
You have to explore for everything (reaching new maps, hidden secret places, getting to see a scene, and getting to new enemies) you'll understand what I mean when you play it, the progression in that sense, feels terrible and it's the big con of it, but you'll get the hang of it, trust me, it can take you 30 mins or 2 hours to notice how to proceed to the next level of underground...
Edit: The game will also get translated very soon, past Nov 17, by Kagura Games, so really, really give it a shot, you'll be surprised and enjoy it, I assure you...
