Deco has some cool ideas and makes a decent attempt at matching the intensity of the song with its pulses. Unfortunately the structuring needs some work. It leaves a lot of empty space between structures and the bg and pulses can't do enough to make up for it.
Playing this you can immediately tell the gp is super skewed towards wave, but it also has a chain of orb heavy cube gp at 40% that I found to be the hardest part. Apart from the less than ideal balancing, it is pretty fun to play.

If you've already beaten plenty of levels harder than this, give it a shot, but don't do it as a hardest like I did.

Straight to the point which is pretty nice and aligns well with the gameplay being so brutal. Currently my hardest :]
