This level hasn't aged too well, but it still holds good features.

A common critique and comment on Dorami would either be aged, contemporary decorations or bad and unintuitive gameplay. While this level has both of these features, it has quite a bit of moments of being good and even ahead of its time.

It makes very good use of grey, white and black; featuring block designs decorated with glow, metal and brick. It also incorporates these colors into the reticle like background effects seen in almost every part and section of the level. The movements of these backgrounds along with the bright pulsing add quite the energy and life to this level matching it with the song used. The consistency of the gameplay is also a plus and the difficulty of each part is sort of relative to each other, making practice runs on this level very straight forward. (Disregarding the beginning part as the intro as used as a difficulty ramp to burst you into the high speed, fast click speed drop)

The negatives of this level are that the gameplay can get very unintuitive and confusing, even for a memory-timing hybrid level. some transitions are quite bad (namely 59%), and some ideas have aged quite badly; the pseudo swing-copter is a good example (53% - 59%). The end maze is where the level peaks in concept. A pulsing, invisible, memory mini cube. This part is very disorienting and not easy to learn and some timings here are a little terrible.

Overall, not bad. Product of its time that's worth revisiting.

Sidenote: There was a reason why this level was regarded as Top 50 most difficult upon release. Now it is regarded as the gatekeeper of the lower end of insane demons.
