Finally got it! By a lot too!

Thank goodness. I choked like 4 runs in level 52 alone (and even more after 42) since I started up this grind. I even had a run that was literally one frame slower than the previous record. Insane.

But this run was very good!! One major mistake but the rest of the run was near-flawless! This one might take some time to beat. Idk if I'll take a break yet. Might be time for someone grab-boosty to take over...

Done on HTML5b.
