Playing as your average ninja robot about town, you begin each game with a sword and a quantum of energy. Leaping across each level leaving a bright trail in your wake, you must destroy other ninja robots to steal their energy. As you get more energy you change color and get bigger, stronger and brighter. This is where the catch comes in! You only get to convert your hard earned energy into game-winning points if you blow yourself up. The more opponents you take out in the explosion, the higher the multiplier, the higher the score!
