This level is a bit too hard for me, but I can appreciate the artistry at work, and relate to the idea of wanting to make something interesting out of otherwise scrapped ideas.
I appreciate your use of my music and in particular the "Underwater Chrome Facility" tileset which, despite being the first custom tileset I ever made, I never actually put to use in a finished level.
Maybe one day I'll manage to beat this legit. I'll let you know if so.
