Kien, a long-delayed action platformer that was initially scheduled to launch on Game Boy Advance more than 20 years ago, has now finally released in 2024 as an exclusive for Nintendo's retro handheld. Though it's unfortunate that the game is only available on a console that's no longer supported by its manufacturer, seeing this once-lost Game Boy Advance title be made available to the public in any official manner is cause for celebration, as it serves as another significant win for game preservation.
