The Champion of Rome: The Fight for Freedom

This is the first game that I have made on Unity, feedback would be very much appreciated.  The game takes place during the time that Titus was Emperor of the Roman Empire, and takes place in a small gallic town which the Emperor likes to visit for the brutal gladiator fights, you are a slave who is forced into the arena with only a dagger in hand, your only hope for survival is to impress the Emperor.  Will he give you the freedom you so desire?
