    Prototyping is a staged process where fidelity and focus change as the idea matures. Treat prototypes as experiments: each stage answers different questions and reduces uncertainty.

    1. Sketches and concept

    Start with rough sketches and notes to capture the core idea. At this stage you are validating whether the concept is interesting and communicable. Keep it cheap and quick.

    2. Visual mockups

    Create composed images or 3D renders that show how the product will look. Visual mockups help test tone, framing, and the initial hook without engineering effort. They are especially useful for pitching creators and producers.

    3. Clickable demos and flows

    Build a low-code clickable prototype to validate navigation, onboarding, and basic flows. This stage is about comprehension: can users understand the interaction in one or two clicks?

    4. Playable prototype

    Now test core mechanics with a minimal playable loop. The goal is to learn what feels fun and what breaks. Prioritize speed of iteration and instrument the prototype to collect feedback.

    5. Pilot and polish

    Once mechanics are validated, invest in art, audio, and performance. Run pilot tests with producers or a small user cohort to confirm the experience scales and meets quality targets.

    Across all stages, log assumptions, run focused tests, and be willing to pivot. Prototypes are tools for learning, not early releases. Move quickly, gather evidence, and use it to make informed decisions.
