Free form Drag and Drop with limited space

reorder items is not usable for most normal users, they just can't do it - I would never use it

one possibility - if there is very little space - is the drag&drop feature "Reveal drag items one at a time" and place all drag items at the same place - but the shuffle function does not work with this arrangement (storyline cannot make the elements appear randomly)

some other options, if you really need shuffle
 - split the one question into two:  5 / 5 or 4 / 6 or 6 / 4 steps
 - remove complete graphic in the drag items and make them smaller, you need space for 2x10 items (because of the shuffle, the drag items must not overlap)

drag&drop in storyline is very limited, the badly implemented shuffle feature prevents many things

hints (usability)
 - add a third layer to your submit button - a simple white rectangle (clickability is improving)
 - the numbers should always be visible, even if all items are assigned
