PRESS RELEASE – July 8, 2025 – Knights of Frontier Valley, the challenging, deeply immersive roguelike RPG, isn’t just a love letter to the golden age of role-playing games – it’s a feat of solo development.
In a brand-new developer blog, creator Martin Menzel reveals how he spent years building his own custom engine to bring the Valley to life – including low-level plumbing work like memory management and rendering, but also features like pathfinding, adaptive game time, weather modeling, and much more.
It’s not your average behind-the-scenes post. Explaining in great detail how characters act and travel in an ever-changing world – whether you’re watching them or not, this devlog pulls back the curtain and shares the developer’s journey to make the custom engine in a way that requires no tech skills to understand.
If you’ve ever wondered how an RPG simulates hundreds of independent lives at once—or if you just enjoy watching a passionate dev go full wizard mode – this one’s for you.
“There are easier ways to make a game,” Martin said in a press release, “but I wanted full code control to build my vision from the ground up, no shortcuts.”
