Dawn Citadel: Light Refraction Physics as Puzzles

Dawn Citadel puzzles use actual light refraction physics (Snell's Law).

Why Use Real Optics in Puzzle Design

Light puzzles often feel arbitrary when beam behavior changes scene by scene. Using consistent refraction rules creates trust and learnability.

When players understand that angle and medium matter, puzzle solving becomes reasoning instead of trial-and-error.

Core Puzzle Grammar

The Dawn Citadel set uses a small grammar: source, medium, prism, and target. Complexity comes from composition, not hidden rules.

Early puzzles teach one variable at a time. Later puzzles combine multiple media and moving targets to test planning.

Readability and Accessibility

Physics-driven puzzles can become visually noisy. To keep them readable, beam paths use high-contrast boundaries and clear depth separation.

The interaction layer is designed to show expected beam preview before commitment so players can reason without repeated penalty.

Production Notes

The practical challenge is balancing simulation credibility with frame budget. Some effects are approximated where full fidelity does not improve decision quality.

The design target is consistent behavior first, visual flourish second.
