New release window came about as a result of critical bugs
We were so close! Just as we got a few weeks away from the February 9 release date of Mighty No. 9, Keiji Inafune announced a new delay over at the game's Kickstarter page. Due to some critical networking bugs, particularly in the area of matchmaking, Mighty No. 9 has been pushed back to a loose spring 2016 release.
Needless to say, Inafune isn't delighted to relay this news to fans who backed the game and everyone else eagerly awaiting its delayed launch on multiple platforms. Here's a more detailed reason for the delay in an excerpt from Inafune's message:
In preparation for the February release of Mighty No. 9 we have been working hard with our partners to resolve any network issues and porting work necessary to publish Mighty No. 9 on the various platforms. However, the issues relating to the network modes were more critical than expected, and it has become apparent that we will need to delay the game from its February 9th release date. We have been working up until the very last moment to resolve these issues in order to make the February release, but it has become clear that we no longer have enough time to fix the issues and have everything prepared for release.
The reason for the delay is rooted in bugs inside the network modes, and specifically problems with matchmaking. 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solution for each platform is slightly different) and the other stems from the fact that the engine we are using is no longer being updated which means adjustments for matchmaking and online code are being made manually (actually reprogramming parts of the engine by the dev team themselves). Unfortunately, this is all a result of miscalculations on the part of us, the development staff. As a result, our fans who have been looking forward to Mighty No. 9 have been forced to wait for over half a year longer than expected, and for that we are sincerely sorry. I want to take this chance to apologize personally, and on the behalf of the development staff.
Over the end of the year break and the beginning of 2016, the development staff has been working on these issues non-stop without break, and thanks to their hard work the end is in sight. We continue to make progress to resolve these last issues that have been holding up the release of the game on the different platforms.
