Studio Doodal will showcase the game to global users during 'Steam Next Fest 2026', which runs from February 23 to March 2. Co-CEOs Kim Min-jung and Lee Gyu-won stated, "With Solitaria, we focused on the essence of the Metroidvania genre: exploration and challenging combat. We designed the 'Pyron Action'—which allows for follow-up attacks upon a successful parry—as the core pillar of combat to deliver an exhilarating and stylish experience." They added, "Within a vast world designed for free exploration, we ensured that harder-to-reach areas offer corresponding rewards. We hope the sense of accomplishment from clearing challenging boss fights and the narrative woven throughout the game will leave a lasting impression on players."

As part of a strategy to expand distribution channels, the team is considering a Nintendo Switch version of Solitaria following the Steam release. They are currently in discussions regarding an eShop release and are also exploring the possibility of producing physical editions for global distribution.
