best level to cure your insomnia with

Like I love really long levels most of the time (See Storm, Light Travel, World Render, Redeemer, Death, etc.), but there’s a point where it just feels redundant. I’m not playing a 10+ minute long level unless it manages to be interesting throughout, which is a task not many can truly succeed at, especially when this level is almost 50 minutes long. This level just goes on and on and there’s nothing that makes it stand out.

(Egoless please save me so that there’s at least one interesting level that’s past the 30 minute mark)
