Every room teaches the next step of the case.

Science is not a detached quiz layer. A formula, observation, or measurement becomes evidence, a key, or a survival tool somewhere else in the castle.

The final analysis board links evidence to conclusion slots around a brass mechanism. — **Reason from records.** The final table accepts evidence chains, explains contradictions, and preserves failed attempts so deduction remains experimentation rather than punishment.

Learn by operating the evidence.

Brew field potions by placing real materials, repair electrical systems by tracing the fault, and use optics, biology, and timelines to separate suspicion from proof.

The alchemy workbench showing three loaded materials and a potion extraction path. — **Chemistry becomes counterplay.** Purification changes how the Guardian hunts. Daze and Shroud create tactical choices. The captured build shows the Chinese localization.

The detective examines a large circuit generator built into a stone workshop. — **Build, track, diagnose.** Three circuit benches teach three different verbs instead of repeating one quiz with different numbers.

A prototype documented in public.

The repository records the revisions—not just the result: rejected realistic character art, interaction failures, spatial tests, visual regressions, and the reasoning behind each redesign.

v0.1–0.5 Movement became investigation.
A maze prototype gained evidence, consequences, STEM gates, and a readable opening.
v0.6–0.14 The castle became a system.
Animated NPCs, dual endings, spatial contracts, and staged optics linked story to play.
v0.15–0.22 The systems learned to speak clearly.
Hubs, pursuit, audio, maps, alchemy, and circuit hardware were rebuilt around legibility.
