yes there are many places to improve on this. but you already did that.
p.s. you opening has shown me a trick to save two seconds when my palm is fixed..oh i am coming back wth a BANG!
oh, dont worry bones, i can improve my 58.xx time, it was more of a "why not" get the gold for me. It took like 10 tries and then i got it. The trick is being throwing caution to the wind and just going as fast as you can. The curves in this level allow for a lot of speed.
There is a certain trick that saves time that I haven't seen someone use yet. I used it and my 58.xx and could easily shave a couple seconds off. But we will never see some crazy trick that shortcuts this level. A couple seconds here, a couple tenths of a second there, but we will approach the best possible time for this level very quickly due to it's design
