Just like you, I started creating a layout with this song years ago, and I can say this is how I imagined a level with this song, this is SICK bro, amazing work.
I feel like the structuring could use some work. In some parts I feel like getting the nightmare vibes because of the structuring. I also feel like the custom orb with the ship gimmick was used too much, even if it looked really cool. Still a great level though.
