I love this game so much! It is a beautifully crafted game that made me smile the whole way. It is so sweet, and has become one of my personal favorites.
Gameplay-wise, it was really unique. It functions like a kinetic novel (no choices) for the beginning of the game, which I normally wouldn't like, but the game does an excellent job of using short scenes and a variety of fun characters to keep things interesting. Then, you get a choice of six objects, which correspond to a character's romance route, but which is which? It's fun to see which object matches which character, and your on your way on a character's route!
I got Ryu's route, which I was surprised as I didn't think he would be included as a romance-able character (I guess I didn't read this page before playing.) I was pleasantly surprised because I loved his route! It was the first VN I've played where you choose a character's route and they try to romance you instead of the other way around. (and he's adorable!!)
Lastly, there is a few mentions or hints of supernatural activities and/or backstories for the characters... this was the icing on the cake as it added a layer of intrigue that just made the game even better! I hope these hints are expanded on in further versions of the game (or at least aren't explicitly denied!)
