I must say, I really love this game, you get a lot of info about Japan and otaku's, it also have a good story, and good music, it's been so long since I have played a novel game all the way through, and feel like I could still could be playing it, so if you're an anime fan and you love novel games, then this is a game for you.
PS. steam says that you can not use a controller, since it heavily needs a keyboard and mouse, the only time you need a keyboard and mouse, is when you need to write your name in the beginning of the game, and when you have to save and load the game, but besides that, then you can use a controller for anything ells in the game.
