Cygames, the developer of Rage of Bahamut, announced during the weekend that it has invested about $680,000 (JPY70 million) in Miracle Positive. The latter is the developer of Japan-based indie game Airship Q, according to VentureBeat.

In Airship Q, players control a cat that was previously a human being. The players must construct an airship, wage war against other airships, and find a magical being that can transform the cat back to its human form. Miracle Positive plans to launch the indie game in Japan on PlayStation Vita. Airship Q is set to be out within this year, the report explained.

Last year, Miracle Positive launched a crowdfunding campaign for Airship Q through Makuake, a Japanese platform similar to Kickstarter. The games studio aimed for $5,000 but it ended up raising $12,000. With the new capital that Cygames poured in, the firm now has more than the cash it needs to work on the project, the report detailed.

In 2013, Rage of Bahamut was ranked among the top-grossing mobile games on Android and iOS, VentureBeat reported.
