Wow, absolutely beautiful! Excellent mood, visually and musically. Agreed about it being difficult to judge where you are in space the further away you get from the center, but the camera action and controls were really, really fun. I found myself testing its limits and trying to barrel roll and zooming all over the place and really enjoying doing so, I was really immersed.
I'd love to see more in this vein, maybe with a concrete rhythm element?
Great work!
