Looking only at the screenshots on the main page, the fact that every single one of them is showing off the world, setting and systems worries me- makes it seem like this is yet another Western Hentai game that suffers from having a lot of story, a lot of systems, a lot of minigames, a lot of story threads setup... and very little to no actual Hentai.
The last Konosuba game I checked out was practically the poster child for that. About 10hrs of gameplay in it, consisting of 2 sex scenes.
How's this one by comparison?
