The narrative leaps 19 years past the events of the original game, which is a must-play, since the characters are intertwined, but your choices directly influence the paths and endings. This time, we're following two main characters simultaneously: one serving time in prison, the other living the high school grind. At certain moments, it becomes hard to tell their stories apart... Experience the raw, gritty reality they both face, feeling every heartbeat and every breath as their fates collide. The prisoner’s world is claustrophobic, brutal, and unforgiving, filled with tense encounters and dangerous alliances, while the teenager’s life is a volatile mix of hormonal chaos, secret desires, and looming threats that could shatter everything they've built. Your decisions will echo across both timelines, forcing you to weigh loyalty, survival, and passion in ways you never expected. The game doesn't just ask you to pick sides - it drags you into a tangled web where trust is scarce, and betrayal hides behind every corner. You’ll find yourself caught between desperation and hope, innocence and corruption. Prepare for a narrative that pulls no punches and reveals the darkest corners of human nature, pulling you deeper into a world where every secret uncovered and every desire fulfilled changes the course of what comes next. The tension builds as these two lives, so different yet eerily connected, spiral towards moments where their realities might crash together in explosive ways. If you crave a game where your choices matter and the stakes feel impossibly high, this is it. This isn’t just a game - it’s a journey through pain, pleasure, and the blurred lines between right and wrong. Will you navigate the prison’s cold walls or survive the chaotic halls of high school? Maybe both. Your story awaits.

In this game of logic, you will play with three completely diverse, but always enticing kittens. First, you must choose from them the one that you are the most enthralled by, and you'll have plenty of enjoyment. The idea is that is where you and your adversary can likely create actions, and since you'll remove sections of the world, the gorgeous one will move between them in any directions. Her task is to draw attention away from the space, while your job is to draw her inside, if there's no other way to do. If you do then, you'll be awarded a prize. And in case you figure out how to catch all of them, you will receive a bonus prize which demonstrates the hot milk these gorgeous ladies crave to the fullest!
