Ninja Boy — About this game
Ninja Boy puts Jack in compact arenas where defeating enough enemies opens the exit. Punch threats, use a limited supply of directional Miracle Kicks and break blocks to uncover useful items. Some enemies need particular tools rather than more attacks, so learning what a treasure does is as important as reaching the door; short passages can also change the route around the arena.
Use A punches on the first enemies and nearby blocks. Try B followed by a direction for a Miracle Kick, then check the remaining K count; save unusual items until you understand which enemy or obstacle needs them.
