I've been playing this game for a couple years now, and jeez! it has really evolved I remember when they only had swords, squares, and ragdolls, i mean 0rava you are doing a fantastic job keep up the good work. :)
Custom Item sharing is coming later at some point. It's both quite complex UI/Workflow-wise, and I didn't want to implement it at the same time as the patch. I needed to get the saving feature working properly first (a bunch of bugs have been reported and fixed already!), so I wouldn't end up bricking all the shared stuff in case I had to fix something major. For now you can contact the level creators and ask if they can share a particular item with you (if it's locked.)
 "Mutilate-a-Doll 2"){kind=icon}
 "Strike Force Heroes 2"){kind=icon}
 "This is the Only Level"){kind=icon}
