The idea is brilliant. And I think one of the similarities I bring is from sky children of light by thatgamecompany. The player goes through heavy wind. I would say the ghost idea is a bit odd considering ghosts can go inside the storm easier than a solid character. And also another thing is the center or eye of the storm is usually still. Have you considered that how you're going to explore that in the game? But overall pretty good so far. Please make the game I think it would have good creative vision.
