Okay, but how?

1. Spam the Cracked Radinax Control Gem on the loading screen. This dismounts you at the start of the dungeon, and sometimes lands you up on the upper platform.
2. Dismount from the Cracked Radinax Control Gem by clicking the red arrow.
3. Use Gunshoes to dash to the last boss.

If you don't land on the upper platform, you can still land in the windy area after the 3rd boss and make it to the last boss in 15 seconds instead of 10.
