Cool, stealthy, and smart. Those are the key traits of a great ninja—supposedly. Luckily, the ninjas sent to hunt you are dumb and clueless. With confused expressions and vulnerable stances, they don’t stand a chance against your strategic skills and giant balls of spikes.
Cut your metal chains, release your spiked balls, and knock down those dumb ninjas to show who truly rules the ninja world.
Features:
• Different ninjas to knock over
• Different Asian-inspired settings where you can perform your ninja skills
• Numerous levels that will test your strategy skills
• A High Score board where you can track your ninja training results
