The launch stream for Mighty No. 9 turned into a post-mortem. Jesus.
Inafune says that 60% of the budget went into the game, the rest on fees and backer rewards.
Their mistake was doing 10 versions of the game at once. They didn't make a version and then port it, they made 10 different versions for all formats.
Actual quote from Inafune: "At the end of the day, even if [Mighty No. 9] is not perfect, it's better than nothing"
