The lasers represent people's line of sight. If you're molesting and a laser touches people get suspicious and eventually you get caught out. I believe progression of the "story" at least in the first game involved swiping their twitter data from their bag or something and posting replies(which you occasionally get blocked for so you have to reswipe data) And getting them accustomed to being molested. If i recall this has new mechanics like being able to chase girls who exit the train and corner them.Yo does anyone have a general sense of how to play this, like what do the lasers mean, is a full train better than a emptier one, per single day train ride. what exactly is the goal etc...., Tutorial was somewhat helpful for basic mechanics and time of day stuff, but I am losing so much (game mechanics and plot) in translation
