This game presents minimal risks. Its RPG mechanics are designed for engagement in learning rather than manipulative compulsion loops. There are no microtransactions, social risks, or significant content concerns. The primary risk is the time commitment typical of an RPG, though the chapter-based structure provides natural stopping points.
