Super Boy I — About this game
Zemina's platform game sends you rightward through four worlds of pits, raised platforms and castle hazards. Jump on ordinary enemies and strike blocks to find coins and unpredictable power-ups. The long, floaty jumps demand care when judging a landing. A tap of the run button while moving builds speed, so allow room before attempting a narrow platform. Reaching each stage's goal is the main task; keep your route focused when hazards crowd the screen.
