Colorful Palette is publishing the console and mobile versions of Egg Hatcher's raising simulation titles, and its Project Sekai rhythm game is still receiving new unit songs. The studio's most recent move is a Vivid BAD SQUAD track added to Project Sekai on September 6, 2026.
Colorful Palette's recent activity runs on two tracks. In Project Sekai: Colorful Stage! feat. Hatsune Miku, Vivid BAD SQUAD's unit song "Seikai" was added as a rhythm game song on September 6, 2026, available from the in-game Present section. The track sits in a lineup with "Kyofu All Back," "Kofukukei," "Haneuta," and "Pentatonic," and it arrived alongside the "After the Fire" event and the "Shady Stare Gacha."
The other track is publishing outside the rhythm game. Colorful Palette is backing the multiplatform release of Egg Hatcher's raising simulation. The first step was Volcano Princess, which was previously only on Steam and gets PlayStation 5, Nintendo Switch, Android, and iOS versions on July 30 for 1,300 yen, with revised translations, full voice acting with new cast, additional stories, stills, and a dungeon. A trial version was already available, and the Steam version is set to receive a free update in October.
A complete edition followed. Colorful Palette announced a complete edition of Daughter of the Volcano, which the studio describes as the 2023 PC game, again developed by Egg Hatcher and launching on iOS, Android, PS5, and Nintendo Switch. Developers Zoi and Fry described the new additions, including full voice acting and Japanese improvements, in an interview with Automaton.
Across the stories, the pattern is a studio working both its own live game content and the console and mobile publishing of an outside developer's simulation series. Nothing in the coverage settles how the new versions have been received, and no sales or review figures appear.
