it was not a bug... There is no sound... didn't hâve the time to put any... I suspect the comment below to be either a joke on the lack of sound, or a person that didn't play to the game and just left that to add a link to his/her game ...
The core idea of the game was to have two different type of control, but I clearly need to fine tune further... I am already working on refining the project. Thanks a lot for the feedback!
