Mighty No. 9 is indeed coming to the 3DS. The Kickstarter, which ended today, recently added a stretch goal of $3,500,000 for a 3DS version of the game, and in the last 24 hours of its campaign, that goal was reached.
All of the stretch goals for Mighty No. 9 were met in its final day as pledges cleared $4,000,000, with over $600,000 added in the last 24 hours. Not only will a version be available for the Wii U and 3DS, but we can also look forward to online play in the Online Battle Race Mode, a playable Call stage and boss, and an optional chiptune soundtrack. Mighty No. 9 is currently estimated to release in spring 2015.
