Lightweight Ninja is a 2-D side scroller that puts you in control of Ty, a pint-sized hero in the midst of a battle for power. On one side you have Elliot Xavior, the charismatic CEO of 'X Industries', who oversaw up the 'Lightweight Warrior' project and wishes to sell the results. On the other side is a soft-spoken Ninja Master named Sentetsu who wishes to put an end to Elliot Xavior's devious plans once and for all.
Which side will Ty choose? Who will emerge victorious? Armed with a wide arsenal of throwable objects, power-ups, and ninja moves, Ty will have to make his way through 15 colorful levels to uncover the truth behind his clouded past.
