Most of the bosses were recorded during the normal playthrough, while some of them were recorded during the boss rush. That's why i didn't get master round after the Kill Pillars fight i already got another round from the previous boss of the same chamber.

I feel like i killed the final boss way too quickly, but i don't think i can do better than this. His second phase always gets me, unless i use a thousand blanks.
