This level uses a large variety of blocks, but plenty of these blocks are in 1.7. (Colored blocks, colored gears, etc.) Also, the drop of 8o is similar to the triple speed ship part of Electrodynamix, where the player is in a very tight tunnel of spikes. At the beginning, 8o is poly-chromatic, containing two colors until the drop. Afterwards, the level focuses on high speed timings and objects that constantly change colors.
The level starts off with a half speed cube segment that requires tricky timing and memorization. The cube is easy to memorize if the song is memorized as well. As the song approaches its drop, the cube sequence will achieve normal speed, and slow down just before the song's drop. After the cube, the player will enter a triple speed ship sequence, which consists of many tight spaces and sharp turns with orbs. Afterwards, the player enters a half speed UFO segment that requires timed clicking or timing. The same sequence (ship and UFO) happen again. Then, at around 67%, the player goes into slow ship mode and encounters a one space ship part with a length of 5 normal spikes. The player then goes to triple speed, and changes gravity very quickly, as seen in the picture. Some gravity portals do not change the player's gravity, which is meant to confuse the player. The slow UFO happens again, proceeding with a triple speed ship sequence.
Then, the player goes through a two space, half speed UFO segment. This is the maximum a UFO can jump (2 blocks) by itself (no orbs, for example). The player then enters a triple speed ship sequence, and must go through a <0.5 block space, followed by invisible ramps. The player then enters one final normal speed cube segment. Zobros's and Etzer's name is located at the end, followed by a triple spike. If the player fails to overcome the triple spike, the player will die at a frustrating 98%. Then, the level ends.
