As a longtime fan of Nu, I'm amazed at what this solo developer has accomplished with functional programming. Built entirely in F#, Nu offers time-travel debugging and multiple programming approaches while staying performant. I've been using it for my own experimental projects and can confirm the functional approach eliminates entire categories of bugs that plague traditional game engines. It's refreshing to work with immutable game states and declarative logic. The project deserves more visibility - it's proof that functional programming isn't just academic theory but can deliver practical tools for real developers. Anyone else here wants to try building games with F#?
