Gameplay
0% - 22% - When the level starts, the player already has to do some ridiculous timings, while the portals and orbs are invisible. These timings are pixel-perfect and very tight. Then, a short ball section appears, with some similar timings. After this, another block section appears with the same timings as before. Then, a very hard ship section comes, which has very tight straight flying in it. Eventually, the ship will slow down, and the screen gets darker. Then, the next section comes.
22% - 52% - This section is at 3x speed, and it is extremely spammy and precise. So many different game mode portals fly at the player while the player has to spam these pixel-perfect timings. Once the section has reached its halfway point, there is a passive but tight wave section, which brings the player into the second half of this section. The second half contains some extreme duals and some extremely tight waves. Once again, at the end of this section, there's a brief wave.
52% - 72% - The speed has now slowed down to 1x speed, but the timings are still incredibly difficult. The start of this part begins with a block section, then it goes to a UFO. This UFO has some pretty weird timings and has a weird click pattern. After this, the speed slows down to 0.5x speed, with another block section. Following this is a ship section, with some very tight straight fly.
73% - 100% - This part is a bit easier than 22% - 52%. It's very similar to it, but it's at 2x speed. This part is the most synced out of the whole level. The first half is just like 22% - 52%, and the second half has a bit of dual-action, but overall it's very similar to 22% - 52%.
