I really likede the story and how you used the theme for the story rather then the literal controls.
The game looks really pretty and sounds really good too. I do think He was a bit too accepting at the end there, but overall love the whole game, great job on that and the story you made for it <3
One thing I do have to note was, that in one of the two puzzles at the end, i thought i couldnt finish it, because your not supposed to be able to cross the blue I assume, but I could walk over it? I think that should probably be the green ground/grass, not blue. I legit thought I had no way of completing the puzzle at first because of it.
*Main other thing I would add to this game i think would be some credits at the end maybe or any kind of ending screen and change the colour of Lux. in the outside part, the character is quite hard to see, becuase of the white colour
