As a fan of Werewolf-style games, this was a story I found myself enraptured by with a constantly evolving cast and story revelation and twists. The game begins slow with allowing the player to get acquainted to the world as an outsider to the actions before getting them involved in it. As well, much of the game subverts the expectation of the player, especially in how players would likely jump to the conclusion that their actions will be the proper solution when that is quickly proven incorrect.
The pacing is an exercise in removing the player from the player insert character. Haruaki Fusaishi is most certainly not a conventional protagonist, with him spending the majority of the story being both selfish, self-centered, and conniving, but never to the point of being the active villain in the story, which was very surprising to see.
Gameplay-wise, issues for players may arise. The game is almost strictly visual novel, with the only player input being from branching path choices, which will largely be pointless as most lead to game over screens. Mileage may vary for each player, but for me, I was not bothered due to the strength of the mystery and character interactions. Additionally, the game is very wordy and does not have a dubbed option, so while I would have preferred to have had the option, I was able to get through it.
All in all, this is a game best liked by people who can handle a strict visual novel, but quite frankly if it doesn't hook you after the first trial, you'll likely never get hooked. I may be rating it too highly for its faults, but even years after playing it, it still revisits my mind, so the impact was apparent.
