Beautiful! I love the effect achieved here, both with the textures, and the music. Very immersive. I hadn't expected the image to end up as foliage in such a way, but I like the look of it!
I played around a bit, but besides walking around, and finding the lights amongst the stones, and a random tree out in the middle of a plain, I didn't seem to be able to interact with anything. The lights seem 'solid' so walking through them doesn't work, the character always collides with/avoids them. I know you said there wasn't much plot, but just wondering if I had found what there was to find, or if there was more left in this mysterious world...
