This level begins with a very hard slow mini ship segment where you can see a Yatagarasu. The player must straight fly to avoid being killed by the red blocks. Then, the player transitions to a very difficult mini wave section where the player must swerve between the tight spaces while controlling it though gravity portals that are very hard to see. Next, the player transitions to a slow ball section where the player must time the gravity changes carefully in order to avoid the spikes. Next, the player transitions into a x3 mini ship section where the player must avoid the sawblades and hit the orb in order to go inside the skull's mouth. Then, the player transitions into a short mini wave part through a tight space and then a mini ball section where the player must change gravity at the right places quickly. Then, the player continues back into a mini ship (upside-down) where the player must straight fly in the narrow space bwteen the spikes. Then, the player changes back into a slow normal wave where the player must straight fly thorugh a short and narrow passage between the spikes. Then, the player transitions to another short UFO passage where the player must hit the orbs carefully to avoid the spikes. Next, the player continues to a x3 speed ball section where the player must time the gravity changes accurately and hit the orbs carefully to avoid the spikes. The player turns into a x2 speed mini ball where the player must time the gravity changes and orbs accurately just as before. Then, the player turns into a slow normal cube where the player must jump through a one block passage between two spikes, which then transitions to another passage where the player must jump over two spikes, hit two blue orbs very quickly to avoid hitting the spikes, then jump over another set of two spikes again, and then the player must jump over a spike and jump again to avoid a blue jump pad trap. Then, the player continues to a section where the player switches gravity on a one-block passage through a pillar of blocks from a blue jump pad. The player must jump carefully in order to reach the next pillar without crashing into the block above them. After the player reaches the third pillar, the player transitions into a short ship section where the player must straight fly for a brief momment through a one-block passage between series of spikes. Then, the player continues to a robot section where the player must first hit a yellow orb a little late in order to reach the next platform without hitting the spike above the yellow orb. After the player reaches the next platform, the player must jump over to the next platform without hitting a spike above the player. The player then must jump across two series of two spikes above and below each other, which forces the player to jump very slightly in order to get through the hole without hitting the spikes, similar to Michigun's part in Yatagarasu. Then. the player must continue by jumping over a fading spike right after the player hits the blue jump pad. The jump must also be high enough to reach the next blue jump pad, which will allow the player to switch back to normal gravity and continue on to a wave section. When the player transitions on to a short wave section, as before, the player must straight fly across a short one-block passage in order to avoid hitting the spikes above and below. This section also briefly turns into a mini wave inside the one-block passage, which forces the player tap very fast in order to avoid the spikes, which is impossible on mobile. The player then transitions into a x3 speed ship section, where the player must straight fly between one-block passages = where then the player must hit a yellow orb right after they go inside a gravity portal (yellow portal) in order to go inside a blue portal, which turns the player back into normal gravity. Then, the player must continue and straight fly through another short one-block passage and hit a yellow orb, which also launches the player into a yellow portal and through another short one-block passage. The player then continues on to a cube section where the player must hit a orb as soon as they go inside the cube portal. The player then must hit a few more orbs to continue into a mini wave section with tight and narrow passages. Then, the player transitions into a x1 speed swing copter section, where the player must swerve their way through very tight spaces through spikes and obstacles. Then, the player switches into a wave where the player must continue to swerve their way through very tight spaces, equivelant to a one-block passage. The player then switches back and forth between wave and ship, where the player must go through a series of one-block passages. The player then goes through a wave portal with a slow speed trigger, where it shows the text "You just survived..." and then a artwork of a demon including inspired creators, the verifier (ToshDeluxe), and the end of the level.
The level was a medium demon, but ToshDeluxe buffed it to make it extreme demon.
Weoweoteo used his evidence from TrusTa, not from looking at the video himself.
Many players have complained about buggy (especially on 60hz) and annoying gameplay on this level. For this reason, the level has received a lot of hate and at its release, there was a lot of controversy surrounding the level (most of which has passed).
ToshDeluxe, the verifier of this level, has gotten many hacking/cutting/auto accusations from people such as MeatiusGaming and Weoweoteo. Weoweoteo made a video about Tosh's defense video saying how he did not hack or cut the level. Weoweoteo said that the level was impossible on 60hz. ToshDeluxe said 83% on the level is nearly impossible and requires "pixel perfect" timing (Unless you have a 144hz monitor.). ToshDeluxe then made a video a day later after Weoweoteo did, talking about Weoweoteo's video that was "proof" Devil Vortex was not verified legitimately. Weoweoteo's video was removed a few days later.
Many players considered this level impossible due to the first ship part and the mini wave spam near the middle of the level.
Warning: It says “F### off” a couple times at the end so be prepared when watching the video.
During the first drop, the level is Rustam's Yatagarasu entry.
