Hey. Audio isn't required, but it is preferred. However, I will not accept your run as the video must feature the player starting the game through the main menu as well as the start of the first level.

If possible, could you please upload a video containing that. Sorry for the hassle, and congrats on such a good run!

It's random! The boss will always attack normally on the first cycle and ground pound on the 3rd, but other than that it's a 25% chance for him to ground pound.

Looks like I accidentally linked the wrong run, updated it to the correct run now.
