Keine's Expanding Class!

, developed by HornyMelon and released on April 28, 2026, is an indie puzzle game with an erotic anime theme that also serves as a parody of the Touhou franchise. The gameplay is based on the classic hangman mechanic, challenging players to guess words related to the Touhou universe, featuring an appealing graphic presentation and a highly praised soundtrack. The distinctive and humorous element is the character's physical "expansion" mechanism, which progresses with each puzzle solved.

Despite simple core mechanics and some repetitiveness, the title has received extremely positive reviews from the community, with a 98% score on Steam, praised for its customization and appeal to both fans and newcomers.
