Mighty No. 9 was expected to meet a 9th February release date, but Comcept boss Keiji Inafune announced in a Kickstarterthat the game would be delayed to sometime this Spring.
The reason for the delay are "miscalculations" on the part of Inafune and his dev team on network coding. "The reason for the delay is rooted in bugs inside the network modes, and specifically problems with matchmaking," Inafune explained. "There are two large reasons for this problem, one of them being the large number of platforms supported (the solution for each platform is slightly different) and the other stems from the fact that the engine we are using is no longer being updated which means adjustments for matchmaking and online code are being made manually (actually reprogramming parts of the engine by the dev team themselves)."
Inafune went on to promise, "Because we are constantly working on it in cooperation with all our partners, we want to wait and make sure that everything is confirmed to be ready before giving a new specific release date. But we expect it to realistically be in Spring 2016."
Mighty No. 9 was delayed twice before pushing the release date from April 2015 to February 2016. Back in October, Infafunethe game would not be delayed again.
