Soul Virtues is a browser-based, fan-inspired personality quiz and experimental interactive experience. Players answer 66 questions to reveal seven independent signals: Determination, Bravery, Justice, Kindness, Patience, Integrity, and Perseverance. The standard assessment processes answers locally, generates a visual personal profile and character-match card, and lets friends compare final profiles through Soul Match without exposing individual answers. It works directly in modern desktop and mobile browsers with no download or account required. Soul Virtues is an independent fan project, not a conventional action game, clinical assessment, or official UNDERTALE product.
