Speedy Dragon — known in Chinese as Yinsu Feilong — is a colorful, energetic platformer released exclusively for the Taiwanese Super A'Can, drawing clear inspiration from the Sonic the Hedgehog series. The player controls a determined-looking young man armed with a baseball bat, charging through six side-scrolling stages toward a boss waiting at each chapter's end. The character builds momentum as he runs and can unleash a charge dash reminiscent of Sonic's iconic spin-dash. Baseballs scattered across the stages award points, item capsules provide bonuses, and springs send the hero flying across the level at high speed. Between stages, a 3D bonus round styled after Space Harrier lets players collect additional baseballs.
