Kickstarter backers of Keiji Inafune's Mighty No. 9 are feeling a little burned. When its Spring release came due, Comcept pushed the release back to fall; when that September launch came on the horizon, the game was delayed until 2016. "We feel bad," producer Nick Yu told us earlier this month. "Really, really bad." The company knows its messed up, and agrees that backers deserve something for their patience. So they're getting something -- on September 15th, the game's second launch date, Kickstarter backers will get access to an exclusive demo of the Mighty No. 9's single player campaign.
