In short, solid, but short. Translation is legible, but not terribly well developed, with the odd typo (but worlds past the 'typical' H-Game translation, translated but not localized).
Having some gameplay, minesweeper's core frame with a bit of an engine twist giving both some room for error and some extra complexity. Fun enough, if you're into simple math puzzles with a dash of probability backed guesses.
Art is solid, and varied enough in the context of the narrative.
The narrative is simple, but not exactly trying to be grand, little more than sexual torture start to finish. It fails the most in the start, in that the mechanics presume you are NOT the displayed character, but rather the aggressor (as the more successful you are, the more she's tortured, rather than the reverse). The narrtive also fails in that the end of each ministory doesn't trigger when you beat its level, but still appear in the replay menu, which could have been better handled, but that could be an error resulting from its translation.
Worth about 2 to 3 hours of gameplay, which is porn top to bottom, with no filler, all solid art and narrative if it's on brand for your kinks. Only modest reply value, depending on how much you like minesweeper.
