I feel it's a bit overrated.
1. The developers said there were multiple endings, but after completing the game, I found only one. At least the other endings don't have any CGs.
2. They added a erotic status bar, but the CG images didn't change. Sexual experiences and events don't change. Although they added pregnancy and childbirth counts, there's no pregnant belly, and absolutely no related CGs.
3. The game is very long, but 80% of it is through dungeons, and the dungeon design is terrible. Most of them are like—you can't open them from this side.
I'd give it an 8 out of 10. Maybe future DLC will make up for it. My native language is Czech, so please excuse my poor English.
