Take it or not, it´s port of the mobile-phone/tablet version of Z, that was released several years ago, it´s not the original Z from the 1995(?) and it´s not remaster build for PC. Just a port, not very good, I´ve actually made it through, it was not all that bad, but it has these kind of typical mobile version-port problems... Notably strange movement of mouse, cause it was kind of build for tablet touchscreen.
