Geometry Dash - Critical Fusion by Nox (and others)
First of all, I am so sorry for the quality. I recently got a new laptop for my birthday, and I'm still experimenting with quality settings for a perfect balance.
This level was very difficult, but I had honestly expected it to be harder. There were only a few very hard parts, such as the waves near the end (somehow fluked 76-100%!).
My total attempts were about 1000.
