A beautiful experience. The gentle ambience and the quiet twinkles of the little whisps really came together to create quite a serene soundscape. The visuals are amazing too. You show a great understanding of colour-theory.
My only complaint is that the game didn't run very well. The occlusion culling came in clutch occasionally, but when I was staring out into far distances the frames suffered. Didn't impact my enjoyment too much though.
Great work with this!
