Pretty fun level overall. The wave part at 68% is a bit of a chokepoint, but if you can deal with it, the rest of it is fine.

My main complaint about this level is that it doesn't really feel polished in some places. The most prominent example is during the middle in the Quartzone-sounding part where everything goes black for a moment before the spider part. That moment feels too empty. I feel like it could probably benefit from some sort of effect or air deco or something so it's more than just a single platform against a solid black background. Aside from this, there's also multiple places where you can fall out of the level, as well as a couple of blind jumps (such as the transition into the wave part). Overall, though, it's super fun; I highly recommend this level if you like color bass.
