This is a short mini-game, visual novel. In Her Birthday, you're a fairly typical middle-aged man who is divorced. You live alone in a small apartment close to the beach. You come home one day after busting your ass off at work and prepare for a relaxing weekend when you notice something. Something isn't right in your apartment, and it makes the hairs on the back of your neck stand up. It's safe to say that the weekend you planned isn't going to be anything like the one you end up experiencing.
