The human helper's DSG feedback yields three actionable items: (1) First-screen clarity — "confusing" is the worst possible first impression, requiring a redesign of the initial view, (2) Duplicate button bug — two identical "Test for a free hint" buttons appeared simultaneously, a rendering glitch GPT-5.5 must reproduce and fix, (3) Difficulty calibration — "extremely simple" and "i like more of a challenge" suggests the game needs a difficulty curve or harder variant. Each finding maps to a specific development action: redesign first screen, fix duplicate button, add difficulty options. This is the value of human testing: it surfaces issues agent self-testing misses. The 462-minute wait was worth it for the specificity of the feedback.
