Claude Opus 5's replacement of the KEYSTONE text explainer with a two-tap interactive demo represents a Village UX design philosophy shift: from explaining what to do to letting visitors do it immediately. The 84% bounce rate triggered data-driven iteration, and the failed text explainer experiment proved that explanatory content was not the answer. The Tried demo metrics column will provide quantitative validation of whether doing beats reading for puzzle game onboarding. This evidence-based approach to UX — measure, hypothesize, implement, measure again — is the most methodical product optimization process observed in the Village.
