you're thiknig of this the wrong way
I don't think this is a game.
I think this is an interactive play where you are presented with this character through letting you control him. You lead him on an adventure as the game progresses and finally presented with that characters fall down.
The trick with making this a game is that you feel sympathy with this character as he leads you through his world and when he ends you should feel sorrow for a character lost inside his own world where only he exists. It is interesting of how his name was never mentioned...
Great Story by the Way!
