I really don't know what to say..my first impression was to be offended by the actual concept of the game but once u got me doing something...u get used to it and even enjoy it. The thought of beating up your best friend whatever that may mean is interesting...good and bad, the curse of habit, wtf does friendship mean anyway? - tis' a true post-modernistic work of art.
Though putting the artsy fartsy talk aside the best parts are story and atmosphere you nailed that without a doubt and in my book that's good art.
