Raw gameplay footage:

Quite a good run. Lost a few seconds due to failing a new glitch on 3-2, getting hit on 4-1 and dumb drum and a few other minor inconveniences. 4-6 seconds can probably be saved off this run without much hassle, likely 10 on a good run. Sum of best says I can shave off 20 seconds so there's still plenty to go.

Frame counted recording from first black frame after hitting start to first frame of Diddy's celebration animation came to 52391 frames recorded at 59.94 fps, which gives 14:34.057. Looks like I was 4 frames off 14:33. Such is life.
