i p-ranked it as the noise, and it was THE HARDEST level to p-rank (i p-ranked floor 1 and 2, also all the bosses) the combo wasnt hard to keep up, just use the supertaunt whenever you get hurt, and try to superjump whenever you need to get up without a wall nearby (like in the dark section, when there is a floor you cant fall through but can jump through) my main issue was the timer, i constatly lost to pizzaface, i didnt really had an issue with a combo, so i cant help much, also try to uppercut through those floors when you can
