Is this the best H-game ever? No.
It's short and the gameplay is very simplistic. There is not much depth as a game in here, it's very linear and the lewd stuff only happens in battles.
That being said as a H-game, the lewd is properly integrated into the gameplay (which I wish I could say about 90% of the other H games). The heroine can be afflicted with all kinds of different statuses that belong to some kind of fetish (BDSM, crest, sensitivity etc.) and they are reflected in battles, both model-wise and in gameplay as they act as debilitating debuffs. Bosses usually have some kind of gimmick that you have to interact or you will lose (aka get the lewd scenes).
If people are wondering why the dev didn't go further with game (even though the basis is there) this is meant to be a prequel for a much larger game that involves the entire cast of characters rather just the protagonist alone.
