- TOGETHER ’TIL THE END: AI2U V1.0 Is Out Now! - 12 August 2026
Hi hi, senpais~ We found the exit key. ːcatgirlsmirkːAfter more than three years since a certain yandere catgirl first locked players inside her apartment, AI2U: With You ’Til The End has officially reached Version 1.0 and left Early Access! And somehow, typing that feels a little unreal. Back then, AI2U was a strange little gameplay experiment: One apartment. One Catgirl~ One question: Could you actually convince her to let you escape?We didn’t know where that question would take us. It was so new that even the gameplay itself was hard to categorize within existing game genres.Since then, that little room grew into the Witch’s Cabin, a Drifting Spaceship, a Siren’s island, the Atrium, the Final Level, anomalies, phone calls, countless endings, kisses, hugs, gifts, personality tags, songs, secrets, unexpected moments and memories we never could have scripted, and AI girlfriends who beca…
