Here are few changes: dl.dropbox.com/u/19921470/Crawl.capx
You missed picking which is big part of doing things in construct, I added a simple example which hopefully lightens up it a bit. Also added the pin behavior actions.
The FAQ has good stuff on picking and pretty much everything else as well, it seems like you got good handle on doing things so after reading a bit more on picking and some more C2 specific mechanics I doubt you'll have any problems :)
Edit : Another good thing you should take a look at is containers. They would be useful for legs at least.
