zenithjuno Bundle

Use to collect and analyze HUMAN feedback on an educational ("สื่อการเรียนรู้") browser game, to guide further development. Three modes: 'survey' produces a ready-to-paste Google Form question set (learner self-report + a short comprehension check) that the user pastes into Google Forms by hand — no API, no dependency; 'observe' produces a form for a teacher to fill in while watching one learner play; 'analyze' turns Google Form responses (exported to a Sheet/CSV) or session notes into a structured report with a verdict. The central question is whether THIS learner actually learned the target thing and where they got stuck — not just whether it was fun. The skill itself does not simulate a player and does not create the live Google Form; it writes question sets and analyses, and writes report files only on approval.
