The earliest reports from the game come from June 2014, when
Mistwalker trademarked the name
Terra Battle. The game was officially revealed through
Famitsu on July 1, 2014. The game was released on
iOS and
Android on October 9, 2014. To promote the game, Sakaguchi chose to create a new model of releasing content. Inspired by
Kickstarter, he created a means called "Download Starter", where new content would be created based on the number of downloads the game would receive. He enjoyed the fan involvement that came with KickStarter campaigns, but did not like the idea of fans directly financing development. Instead, he chose the "Download Starter" model, which was aimed to create interest in the game after it was already created. After the game had been downloaded 1.6 million times, composer
Kenji Ito joined the project, with
Kingdom Hearts series composer
Yoko Shimomura joining him after the game had been downloaded 1.7 million times. To commemorate the milestone of 1,800,000 downloads, a new musical track by famed
Chrono series composer
Yasunori Mitsuda was added to the game. The final milestone, at two million downloads, would have been releasing a version of the game on consoles. ==Reception==
