This is easily the best game on this site (and I have played tons of games from this website).
It has the perfect story-to-sex-scene ratio. You'll never be hungry for new scenes, because they're just around the next corner. There are 67 girls to have sex with and many of them feature more than 1 sex scene.
The semi open world is fun to explore, yet there's no space wasted with emptiness. The game respects your time highly, you don't have to repeat the same tasks over and over again. You also don't have to go through the slow basic intercourse scenes with every new girl you face as in other games (talking about BJ, HJ, TJ[...] etc. here).
Instead, you always instantly get full sex scenes. This comes with the burden on the dev's shoulder to get really creative with angles, poses and situations to keep things interesting, as he can't behind doing the same boring stuff over and over again. And he does absolutely master this burden. In no other game with such a high production quality you'll find such a variety in girls, sex scenes and everything else.
Another cool thing: Since this is about a world with monsters and monster trainer, dialogues aren't smalltalk about "how's school" or your homework or what someone wants to eat tonight.
Instead every girl there has a purpose in the world, something they strive for, a goal they pursue. That's pretty cool.
As I mentioned earlier, the production quality is enormous. I also didn't meet a single bug in two entire playthroughs.
