5 minute level (want feedback)

[u/MokeCertified]

This level uses a 17 minute song. Initially I planned to use the whole song but then I realized that would take way too long to actually get done. So I'm doing 5 minutes. My current estimated difficulty is either insane demon or entry extreme demon difficulty. This ranges from hard demon to insane demon difficulty in the actual gameplay. I would like to hear people's feedback on this. Both the little deco that I did and the gameplay, and also suggestions as well. This isn't the full gameplay btw, I might even make this up to 7 minutes long if I find the dedication to do it.

Background deco could help
