Has anyone played it and is the game any good?
Yes and no.
porn-wise: Meh. The scenes are okay at best. Nothing you won't find done better in many other games.
Actual game-wise: Absolutely horrendous.
The amount of exp the game showers you with makes the combat trivial to the point where I was just holding down a button for all fights, including boss fights.
The dungeon crawling is tedious to the point that it's clear that the dev didn't have any grand plan in mind and just needed to fill extra space on the map so shoved them full of dead ends with maybe an item you won't use cause the combat is trivial.
I was consistently 10-20 levels over the recommended level for any dungeon cause that's how much exp I got simply from getting through the last one. No grinding required.
If you do get the game then don't do what I did and play the game normally. Choose event mode. The gameplay's so shit that even the devs felt an option to completely avoid it was needed
