Congratulations, you completely failed to complete the prologue of the game which is needed to set up the plot for the rest of the game. Once you complete the prologue (more or less by reaching the Abbey), the world is completely explorable. They have to do something to make sure you do the prologue - what would you prefer, a narrow path surrounded by cliffs all the way to the abbey?
Either way, making a youtube video about your failure to play the game as intended within the first 20 minutes of the game and say 'what a shame' is kinda lame, man.
