I have a question for you. I am looking for a game that might be adapted to utilize in stroke rehab. Your game has some interesting potential. The problem is that it requires the user to "grab" the blocks in order to play them. People that have had a stroke often do not have the fine motor control to manipulate the hand controller. I would like to use the game to promote gross motor arm retraining. Any way to tweek the code so that the user only has to touch to grab a piece? Does that make sense? Would also be great to have a mode that requires two hands to grab thereby creating bilateral arm activity. Would like to use this for research into clinical application for stroke rehab.
