I found an easter egg. If you collect all of the blue orbs on the title screen thing, you unlocka n easter egg and a number. I think the number is used in Llama adventure to unlock the Penthouse!
Got -11 on my first playthrough, though that involved making sure I got par at worst on each level. Saved one stroke on 7, 10, 16, 18, 19, and 29, plus 2 on 28 and 3 on 26.
What's the 20043 for? Is the previous poster correct, that it's for "Llama Adventure"? Never even heard of that one.
