Wow, this style is really stunning! It's an art style that goes really well with the music too. It has a vibe that's kind of Spiritfarer-esque, and a bit of Night in the Woods feel to it as well—pretty cool. I feel the subtle lighting effect are quite fascinating too; they add a nice layer of depth.
It's quite fascinating how you control such a tiny character within huge places. The only thing that I think would make it more immersive ... currently the character seems to slip quite a bit in the environment... I can imagine it being cool to more tangibly feel each step, the character's movement.
