As others have said, this is mostly a montage of visual effects that aren't sewn together by any narrative, worldbuilding elements, or gameplay. The creator certainly has some potential in environment creation but the presentation of this ends up mostly being a tease as there isn't really any actual content behind the imagery. I think if they were to work on turning their style into an actual game then there is a lot of potential for some awesome ideas here, but as it is it mostly comes off as a portfolio of assets.  The good news is I think the hard work has been done and adding things like a story, smoother and more interactive mechanics, and some world continuity shouldn't be too much additional work.
