What worked 90% of the time for me (tested it) on level 45. Drop on the starting block. When you are left of the lower block, double click it. Most of the time you will not launch but rather just "drop" to the side enough that you will make it. +if it worked for you.
Me:"I had no idea an excavation would take 1 octillion to fund."
Archaeologist: Well expenses do get pretty tight."
Me: "But an octillion! it took me an hour of teaming up with fairies, buying a 10 dollar farm and a billion dollar farm and moving my finger just once to get 4 septillion gold yet the gold never stops coming out even though I can only see that there is about two thousand in there."
Archaeologist: "well it only increases by 0.2 every time."
Tip: On round 34 you can go through the saws on the way down just get on the way left edge of the firs single block. This helped me get the yellew bird first try.
