Grounding developer Yukio Futatsugi said in an interview with SourceGaming that working with Nintendo on this eShop exclusive game was "a really good learning experience":

"When developing with Nintendo, I learned a lot, and Nintendo isn’t shy about giving really direct criticism, and a lot of times the ideas that I came up with were torn down because Nintendo said, ‘No, this is not a good idea, you could do this better’ and most of the publishers that I’ve worked with don’t do that. They sort of try to mask whatever isn’t developed properly and move on with development, but Nintendo wants to make sure that the game itself is good, so they give a lot of criticisms, and that was a really steep learning curve."
