Sound Qube

Different types of cubes respond to different types of pulses; once identified, the player can mark the color of a cube. Red, Blue, and White cubes can be eliminated by locking multiple of the same color and firing a sonar pulse, while Purple "Core" cubes can also be locked and eliminated solo, though attempting to eliminate a cube as the wrong color will penalize the player with a loss of energy. The goal of each stage is to find and eliminate all of the Core cubes, which will respond to both red and blue sonar pulses, before the time energy runs out.
