I'm not sure I've encountered a VN that has engrossed me as much as this one did. From my very first (highly unsuccessful) playthrough I knew I had to play and replay and replay this one until I unveiled the truth.
All of the characters are endearing in their own way, and also have human elements that can make them irritating, and yet I always felt a moral duty to try and get everyone across this darn lake in one piece.
I will proffer one piece of advice. Stick with this one, because no matter how many times you traverse this game there's something else lurking around waiting to be discovered. Explore every route, pay attention to those response options and prepare to die, die and die again!
An absolute corker of a game, one of the best VNs I've ever played.
