Functional Game Logic with State Pipelines - F# Part 3 [Episode 003]

In this episode we start building the basic logic for our text adventure game by constructing a logic pipeline that transforms the game world state. We cover match expressions, parameter destructuring, and a technique known as Railway-Oriented Programming.
