No professional, but the physics-based puzzle game Bubble Ball is programmed by a 14-year-old kid called Robert Nay.

The game, mainly for the iPhone, released on December 29, has already reached the record level of 2 million downloads displacing Rovio’s popular Angry Birds Seasons as the No.1 free title in the iTunes App Store, announced Ansca Mobile.

I had no idea that it would do so well and become the number one game, says young Nay.

Nay has already planned for his next work on a possible paid Bubble Ball add-ons with the money he earns, says

Nay, while programming Bubble Ball used the software Corona SDK designed by Ansca Mobile.

Ansca Mobile also confirmed the game’s popularity has skyrocketed, culminating in its No.1 spot on January 13, 2011.

Nay attributes his success to the support from his parents while programming this tough game.
