I know I'm a little late to the party but I started working on this as soon as I got the idea. Some fun facts:
I was planning on replacing the A I U E O sounds with ghast sounds, but I could not find any clean versions of the trailer audio without the vocals and voice over. I decided to just own it and even included that text box and hand cam footage.
The background is supposed to be based on the Soul Sand Valley fog color, and the ring/hoop is based on a nether portal. I was almost going to make an actual blocky 3D nether portal, but I couldn't figure out the camera angle and focal length. You can actually see it in how I had to skew the tile ground—I cheated the camera.
Anyways, I'm hyped as fuck for Groove! Maybe this hype train will be the push I need to finish all those other animation ideas I've had on the backburner.
