Back when the Switch was almost going to be unveiled, there was a teaser for an exploration game which featured a kid and his dog.

I forgot the name, and while browsing the internet I realized that it hasn't been mentioned since. I believe it was called "Seasons/story of heaven" or something along those lines.

Seasons of heven.
Supposedly based on a book.

"Seasons of Heaven will take you from deep inside of a mystical forest at the beginning of time all the way through to the twenty-first century and the fall of civilization. It will take you on a journey with Yann, a young boy with Asperger’s syndrome and his faithful companion, Ani, a French bulldog who Yann is able to communicate with through telepathy. As you follow along on their journey you’ll have the opportunity to meet the rest of the major players and bear witness to the enlightenment of some and the demise of others. This story will allow you to experience the awe of discovering the most beautiful, magical place that ever existed while at the same time staying only one step ahead of the dark and vile underbelly of the human race. Most importantly Seasons of Heaven will awaken your imagination and open your mind to possibilities you may never have considered. It will have you on the edge of your seat as you question everything you thought you knew about humanity and begin to realize that the possibility of things existing that can’t be seen with our eyes but only felt within our hearts and souls, really do exist." - quote

I remember thinking some of those early shots they showed from it, featured graphics beyound what I thought the Switch capable of. It looked good. No idea why it wasnt at E3.

I hope they show something soon. It looks amazing, and the concept sounds like a better version of "The Last Guardian"
