This is a 30-40 hour JRPG that comes with a couple of porn doujins baked into its sidequest/post game. If you approach it with that mindset, it's pretty good. The combat is a bit generic and it's easy to miss things that make it go much faster - weapon shops are relatively rare and it's easy to miss sidequests that give good equipment, and one character relies entirely on finding items for her scattered throughout the dungeons. If you don't find those items, she gets barely any skills, and is pretty useless.
But the game's writing is very strong - it's not *incredibly* deep, but it gets across its themes well and is pretty to the point for its length. I could easily imagine this same story taking 80 hours to tell instead. The characters are all likable, and there's some pretty funny lines.
That said, again, this is largely an RPG, and even taking it on that metric, the combat is nothing to write home about, and while the music's good, it feels like there's maybe 20-25 songs in the whole game. As good as the major boss theme is, you'll get tired of it by the end. So it's not flawless or anything.
In terms of the porn content, the content in the sidequest area is pretty forgettable, just a few generic scenes with minor variations. There's a bonus area you can go to after getting a game over that has better and more varied H content, but the scenes there are still fairly short, and it's all extremely dark content - BDSM, slavery, risk of death, some violence, etc. No outright gore, but it's pretty hardcore. If you're into that kind of thing, there's a decent amount there, but I still wouldn't recommend this game solely for the H content. And if you wanna see it, I'd recommend saving it for the late game, when you have all seven main party members.
So to go back to my main point - this is a 30-35 hour JRPG, SNES style, with some minor h content as a bonus. Think of it like if a download of FF6 came with a folder with a few hentai manga of it. If you approach it with that mindset, you'll probably enjoy it. If that doesn't interest you, this is a skip.
