A Steam store page has gone live for Chrona & Sirona, a command battle RPG in which mood swings directly translate into combat strength. Also today: the charity event RTA in Japan Winter 2026 was announced, and a release date was set for PengPong, a roguelite action game from Korea.

Mood Swings Change Your Stats in Chrona & Sirona, Solo Developer Kiichi Opens Steam Store Page

Chrona & Sirona, a turn-based command battle RPG developed solo by Kiichi, now has a Steam store page. The two protagonists are Chrona, a student at a magic academy, and Sirona, a mysterious figure who looks just like her. Chrona spends Tension Points (TP) to activate skills: the higher her TP climbs, the more her stats rise, and once it turns negative, they fall. Kiichi has been building the game since around 2025 using the development tool RPG Developer Bakin, and plans to make a demo as well. It supports Japanese and English, and no release date has been set yet.
