Very nice Brian! I am glad you didn't stop at 59.78, when you broker the 1 minute mark.
btw you got to 57.xx in far lass tries than it took me. I think I didn't reach 57 until about 15,000 tries, and ended somewhere around 16,000 tries.
I think the 2 toughest and most frustrating parts of this map are the dino's spikes and the "O" in Kong. If I could redo it, I might have given more clearance on the overhanging ledge above the 5th spike. I also might have laid down a flat grounding above the "O". I don't think it would have altered the end time much, but I think it could have improved the 'failed/completed' ratio and the frustration ratio.
At any rate, those who take the time to master this level will find that even those 2 annoying parts can be overcome with practice.
