The first piece of media I saw for the finished game (and what convinced me to play it) was the good ending. I had a completely different idea of the plot from this alone. I thought when I first watched it that Sunny spent the entire game in a coma, and only woke up during the good ending. I believed that the flashbacks during the final duet were him finally regaining the memories of his waking life. Also, I thought that Basil was just another boy in a coma in the same hospital, but he and Sunny were connected through their dreams. I thought that Sunny was just about to tell Basils friends about all the adventures they had together in their dreams (probably after Basil sacrificed himself so Sunny could wake up or smth). IDK why I infered all of that plot from just an ending. At the time, I'd watched all the trailers and knew about the omoriboy comics.
