I work with a research group of the McGill University who has developed a computer simulator for handicap people. Your program is used within a clinical study where the goal is to test the validity of this simulator. I have to write a user manual explaining how to use your game. I am not sure about some details of the game use (e.g. how to look backward and throw things in that direction). Could you tell me where I can find these instructions? I cannot seem to be able to find them on internet.
