Comcept is expected to finally release their side-scroller action game Mighty No. 9 this month, and Keiji Inafune shared some of his thoughts and struggles that went into the development of the game in a recent interview with 4Gamer via Hachima.

Here are some of Inafune’s quotes from the interview:

“We deeply apologize to the fans and backers for having taken much longer than expected. I learned again how difficult it can be to make a game”

“(The reason of delay) was not because we were shorthanded, but due to how we were going to sell it, and then biting more than we can chew after declaring that it will be released for all the hardware. But it was a good [learning] experience.”

“What I thought about most while making this game was ‘I want to show the greatness of Japanese games. When listening to fans of Japanese games abroad, you often hear them say ‘Japanese games used to be great. I worked on this game in hopes of getting those people to say ‘this is good’ again.”

“One more thing I’d like to say is that Mighty no. 9 is a [set of] ‘contents,’ meaning it’s not just a game. We’re also moving forward in an anime and live action film for it. Development for a sequel is already in our minds, and we all share the feeling of ‘we’ll do it even if it doesn’t sell’.”

Mighty No. 9 will release in North America and Japan on June 21 and Europe on June 24, 2016 for PlayStation 4, PlayStation 3, Xbox One, Xbox 360, Wii U, and PC.
