: Sam fires a magnetic tether. It only sticks to metallic "Retro-Tech" surfaces. While tethered, Sam’s momentum is preserved, allowing for wide swings.

Rouse outlines a specific iterative workflow to ensure a feature actually works in practice: : Sam fires a magnetic tether

Before writing a single line of code, define the of the game. This is a single paragraph that serves as the "litmus test" for every feature. If a feature doesn't directly support this focus, it should be cut or revised. : The specific rules and player inputs (e

: Fast-paced, non-violent action using inventive environmental interactions.

To develop a feature using the principles from Richard Rouse III’s , you must move from a central vision (the Focus) to an iterative implementation process where "fun" is the only metric for success. 1. Establish the "Focus"

: Add the actual mechanics (combat, puzzles, etc.).
