i've been following the impossible levels community since 2.0 so i think i can say with some certainty that this is the first impossible level really had the effort of a normal relatively high effort level put into it, and rather expectedly it's become one of the most famous ones, only a few steps behind stuff like silent clubstep

and people may be surprised to learn me, someone with veteran, arthouse, whatever tastes, really likes this level! the decoration is fairly cliche (see adamantium core for this theme done right imo) but passable, but the gameplay, especially with the grinding synth in the drop, just works, so over the top and terrifying, and so appealing sensorily, extreme wave spam really just feels like the right choice for this song. an idea first proposed with silent circles finally fulfilled, for better and worse
