I played this game on a whim, mostly because it was free and I had heard some vaguely interesting things about it. I can’t really say much about it by its nature as a VN, but I will say that I think it really does deserve to be played regardless of what you think of that particular genre.
Without spoiling anything, it does such a good job on lots of different levels; it draws you in and makes you like the characters. It lulls you into a false sense of security and then when you think you ‘get it’, it manipulates you into making the choices that you think will result in a nice ending.
Although I didn’t fully experiment and so dont know if there is a really ‘good’ ending, it does a great job making you feel like you fucked up, after making you think you’re being clever. It breaks the fourth wall in a way that is really effective, and hit me harder than any other usage of the technique I can think of.
In short - it’s a great game, and only a few hours long so go play it - unless you are extremely averse to having your emotions toyed with!
