Really? This game doesn't even try to be a good copy paste of AZL. Is it so difficult to create an adequate plot for a porn game? AZL had interesting story, expecially for a porn game, and believable characters that weren't trying to jump on MC in first few days. You actually had to corrupt them little by little and that's what made that game excellent, at least until 0.7 version approximately, where Nergal chose quantity over quality.
And what do we have here? First appearance of zombies is terrible: MC just goes to breath fresh air and voila! - it's zombie apocalypse now! Characters are boring and cliche'd: a typical mother, oh, I'm sorry "Maid" and "Tutor", who's obviously a sister with a typical and boring "older bitchy sister" character. First scene with mother is a copy of Town of Passion's scene which is a copy of A Zombie's Life scene - bathing with mother. First scene with sister? Don't know if I should laugh or cry: on second day of zombie-fucking-apocalypse they come to some old shed with (sic!) glory hole and MC just decides to stick his dick in this hole and his sister, I mean "Tutor" decides to suck it. Why? Because why not!
P.s. In AZL even the fact that main hero have big dick explained by virus and here? Nothing. He just a boy with unnaturally big dick... Awesome twist.
