Indie developer has his game shot down by Nintendo for Switch release, discusses why that might be

Developer Adam Ashbaker is trying to get his game SpikeBlade released on Switch. After issues with getting the game on the iOS App Store, Ashbaker reached out to Nintendo about getting the game on the Switch eShop. After a short amount of time, he received the following response from Nintendo.

Thank you for your patience during our review period. While we appreciate your interest, we are not able to grant you access to Nintendo Switch development resources at this time. We encourage you to watch the Nintendo Developer Portal for updates as more information regarding Nintendo Switch development will be made there in the near future.

While not given specific details, Ashbaker believes his game was shot down because he'd be self-publishing the title, and he hasn't created anything successful previously. Again, while Ashbaker hasn't gotten any exact reason for the game's block, he doesn't believe it has anything to do with the game's quality.

What do you think? Does it have something to do with the quality of Ashbaker's work, or lack of published titles/publisher?
