The story is amazing and the characters are either cool or cute. Sometimes both.
But most of the time I feel the way your decisions influence the different story events is nonsensical! For example, you answer a SMS from a character asking you which is your favorite T-shirt color and your answer makes the difference between a peaceful future or world destruction (I made up this, is just an exaggerated example). I think they are portraying the butterfly effect waaaaaay too much.
Is a good game, despite of this.

PD: I'm waiting for Tutturu to come and comment "Tutturu!"
