Well...not that I don't like where your going....
But....'where' are you going with this?
How am I suppose to build a proper matching robot if I don't know what the robot's suppose to look like!?
Also, it's kinda a pain having to accurately grab pieces flying and bouncing, you've got a nearly perfect match and BOOM, you mess up the whole thing desperately trying to reclaim your arm only to misplace the head and torso.
It's a very unstructured game overall.
