The game presents minimal risks. Without microtransactions, loot boxes, or subscriptions, there are no monetization pressures. Dopamine manipulation mechanics are largely absent. While competitive play might introduce minor social comparison or toxicity, the absence of stranger chat mitigates significant social risks. Content risks such as violence, sexual content, or strong language are not present.
