First of this is extremely difficult which isn't necessarily a bad thing except that the keyboard + mousecontrols and button layout are also incredibly difficult to use. Choosing items with the scroll wheel is an ingenious touch. When I realized I had more mobility options for each item I was able to expand my range of abilities in order to get the key. I couldn't seem to get the right coordination to pull off the intricate maneuvers. It would be nice to see this concept develop further.
