Gameplay
Dudex: The level starts off in a mainly blue part with all kinds of orbs to hit. It is played entirely in cube form and has a mechanical/electric vibe to it. It transitions into the next part via a reverse dash orb.

Serponge: This part is decorated in a very similar way, but with a more "active" background with the use of rotation triggers. This part is played entirely in dual cube form with even mire orb timing and some dash orbs at the end.

Manix648: Starting of with a short quad-speed ship, you then go into a section with a lot of gamemode changing and flying enemies everywhere. A robot, ball, cube and spider all follow eachother in the span of 4 seconds to which it goes into a normal speed cube and ufo before ending with a robot with two green orbs and a dash orb.

Vlacc: The fist half of the part is very colorful with everything switching between different colors constantly, and once again; tons of gamemode changing. The second half is however played in only black and white with a cube, ball and ship; all with tight spaces.

Rustam: Being played in only slow mode, this part's difficulty comes mainly from the hard manouvering of the ufo and ship in the beginning. This segment is fully colored in purple and contains one of rustam's high quality skulls. Then comes a ball and a narrow wave before transitioning into the next part.

Trivia
This level, unlike the other two levels in the "Sonic-series" (Supersonic and Ultrasonic) was uploaded to ViPriN's account unlike the other two which were uploaded to ZenthicAlpha's account. This upset some as they did not feel like it was a true successor to the other two.
