Pang

In the game, the Buster brothers must finish a round-the-world quest to destroy bouncing balloons that are terrorizing several of Earth's landmarks and cities. The fight to save the Earth begins on Mt. Fuji, Japan, where the brothers must pass all three stages before moving on to the next location. The basic gameplay is identical to a much earlier 1983 Japanese computer game called Cannon Ball (also released in 1983 on the ZX Spectrum as Bubble Buster). Cannon Ball was made by Japanese publishers Hudson Soft, and possibly inspired Mitchell Corp. to make Buster Bros. six years later.
