The art is really great on this game. You did a great job on that front. The shader works well and looks very nice.
The gameplay, however, is lacking with not much to do aside from walk forward and read the story.
The story itself is fine, though I didn't get why the ending choice had to be made. I never saw any reason you couldn't do both, but maybe I just missed something.
Good job overall! You have a great visual framework you can expand on or develop the game into a larger experience
