... Why don't you play on something above easy? Like maybe Normal mode? RiT adds points crazily from all the stuff it wants you to pick up.

In DD, the only things you need to pick up are the bouncer ammo, stand at a certain coordinate and then hope they'll bounce off the wall downwards instead of back up. That and two apples (I accidently picked up an extra two from stuff that didn't fall down)
EDIT- I forgot the weapon shortcuts don't work in a macro. Need to rerecord later. Anyhow, here's the final score from my Recording session:
The only way I could possibly get more on that level on hard mode is if I get hit by a Dragon prior to getting a certain Carrot I typically stand over.
