I thought the writing, characterization, and voice acting were surprisingly poor, it's a game that requires the chemistry between the two characters to really sing but it just falls flat. Some people complain about the plot itself not going "anywhere" but I think that would have worked if the fundamentals were stronger. (Far less important but I also really didn't like the animation and character feel.)

I vastly prefer Gone Home, which is a very similar type of game, with much less flashy visual style but the characters, voice acting, and storytelling are handled, imho, perfectly.
