The panel was filmed by 2 Player Productions, which will also be delivering a behind-the-scenes look at the development of Mighty No. 9 — as it is doing for Double Fine's Broken Age and Massive Chalice — in the form of weekly videos released every Thursday.
Inafune's reveal of Mighty No. 9 was a surprise even to the panel's moderator, USgamer senior editor Jeremy Parish, who wrote on his personal blog this week that he "knew Inafune was announcing something, but not the particulars."
2 Player Productions said it already has a great deal of footage for the Mighty No. 9 documentary from trips to Tokyo and Osaka, Japan, where co-developers Comcept (in both cities) and Inti Creates (outside of Tokyo) are located. The full documentary will only be produced if the game's Kickstarter campaign hits its next stretch goal, the $1.75 million level.
As of this time, the funding drive has pulled in more than $1.65 million, 184 percent of Comcept's $900,000 goal, with 26 days left in the campaign.
In addition, 2 Player Productions released a video with Mighty No. 9 composer Manami Matsumae playing a segment of a piece from the game's score on a piano. You can watch it below.
