You can't do IL speedruns of any levels other than 8-4 because they are all perfected. 8-4 speedruns are in the category extensions.

Might be a bit farfetched, but some glitches might also occur based on what objects and their positions are in the start, as each time you start the game, the objects at the start screen differ and have different locations.

When you complete the frequency section (2nd section), a cube planet flies across the screen, yet it seems that it is random. The time the planet flies across the screen differs in a range over 20 seconds (sometimes at around 1:35, sometimes 1:50). No idea if this affects any other gameplay.

Sometimes in the third section (cube planet), the robot launcher comes earlier or later, so that it may be impossible to hit the planet immediately as it comes out.

I don't know if the planet that appears after the frequency section has anything to do with the robot launching section, just putting it out there.

In YTreds' run, he used both the L and R joysticks, which make the cursor move faster. How would you hold your controller (Switch Pro) to hold both joysticks while also pressing the other necessary buttons? (A, Y, ZL, ZR)
