In the appartment, you have to click "storm out", then move slowly the curser in the right direction to caputure the girl. On the streat, to kidnap the girl, you have to click on the hand then move slowly the curser in the right direction.
Yeah it lag a little and there is this problem with save, but that somehow a good game for those who love this (too rare) genre. Would be a lot better if there was a little more indication on what to do in certain scene and more possibilities, but that's still a lot better that a lot of implayable crap from japan that arrive in western world.
