I don't really understand the controls, there is like one zillion things you can do but I don't find their use (I don't know what I did once to crouch, dunno how to shoot the gun I'm supposed to have). Text flashes a little fast, or hides on the background when the white letters are over a white wall.
I liked the siren, sounds are pretty good too. The story is kind of unique, I'm sure my mom would never go to Japan.
