The experiment ii has quite a lot of visual cohesion and a pretty strong theme, which was fairly uncommon back in early 2.0 when it was made. It's meant to resemble a broken down, somewhat post-apocalyptic science facility, and I think NachoLag executed this pretty well with the blend of mechanical design elements and movements present throughout. The main structuring is done using a long corridor filled with metallic, red/white spikes surrounded by black ground spikes, which is a pretty cool aesthetic since the usage of the decorative spike blocks inside the structure generally resemble shards of broken metal. The staccato, bouncing movements seen at specific points in the level accentuate this as they feel like robotic elements that are not working correctly, which is a really nice touch to add to the calmer break parts of the song. Due to the time period The experiment ii was made, there's a noticeable lack of general polish brought on by the community's unfamiliarity with the editor, and I personally don't mind this as I think it ends up functioning more as an aesthetic element common in levels of this time, but I'd have loved to see more creative usage of objects such as fire, animated creatures and structures inside the corridors to further elaborate on the overall theming. Additionally, the pulse work is pretty sloppy and the level only uses red, white and black, so some hue variation and better synced effects would have been nice additions for better song representation.

I'll definitely be checking out some of NachoLag's other levels, because The experiment ii is an intriguing level in most fronts despite its lack of polish or execution. I would recommend this for Star Rate.
