Hentai 2+2=4

Hentai 2+2=4 is a small casual puzzle game that launched on October 5, 2018, shipping as a self-contained product with 12 pictures and simple math-based gameplay. A paid Art Book DLC followed on October 31, 2018. The developer issued a bug fix on October 17, 2018 and a feature patch on December 7, 2018 that added a "Pro Mode" and new achievements — the last substantive update the game received. Since December 2018, all news posts from AFBIK Studio have been announcements and releases for entirely separate games (Cyber Furry Girl, Hentai Killer, Hentai Climber, and Hentai Killer: Girls & Chess). None of these posts reference any new content for Hentai 2+2=4 itself. The store description mentions "Trading Cards: SOON," but this appears to be a remnant of an unfulfilled promise from the original 2018 launch period, and no trading cards have materialized in the years since. All released DLC is accounted for, no future content has been announced, and the developer's attention has clearly shifted to other titles. The game launched as a complete, finite product and received its final update on December 7, 2018.
