New app Tower of Saviors is at the top of its game
Struggling young entrepreneur tastes success with his winning mobile game Tower of Saviors

Eighteen months after quitting his job to start his own business, Terry Tsang Kin-chung had just HK$9.96 in his bank account.

One of the firm's games has been Hong Kong and Taiwan's highest-grossing Android app in the past two months.
Released in January, smartphone game Tower of Saviors has attracted more than five million downloads worldwide - with three million from Chinese-speaking users - making it one of the most popular games on both Android and iPhone systems in the two places.
Tsang said a sixth of the downloaders paid to play the game, and its daily average revenue per paid user was US$40. "Starting my own business had always been my dream," said Tsang, 31. "I thought of giving up … but I really wanted to keep doing what I liked."
Tsang, who has a master's degree in civil engineering from the University of Science and Technology, quit his HK$40,000-a-month fund-selling job in June 2008 to start a creative business company with his brother.
