A really solid game. 4/5
Plenty of content, good story and bunch of well developed characters that make those important moments worth it.
Map exploration is the standard. There is not much hand holding, and it lets you explore it to find those "secret" H events. Map is small. however, but that may also be a plus for some people that do not want to waste too much time.
Battle-gameplay has 2 types of monsters, first type that pulls you into traditional turn-based gameplay for those that like that, and second type that you just run over for XP, which is amazing if you just want to follow the story.
Base art, at least for me, is the biggest downside of this game, since it kinda hangs on the average when it comes to quality of it. HOWEVER, usage of it is really good. So even if art and artstyle are not really up to my tastes, they are still of high enough quality to be enjoyed.
Variety of H scenes is also solid, but story that surrounds them is what makes them really good.
Type of NTR presented is meh, since they is no buildup for it, and they kinda just jump into it willingly. No trickery, or proper time for corruption , just plap fiesta. But again, it is really well done, so you'll enjoy it even if there isn't much buildup overall.
Conclusion: 4/5
It hangs in the upper parts of RPGM NTR genre, with really good overall quality.
