Thanks for your comment, and yes, the prologue is quite linear, but at the time I thought it was a good idea to do it that way. It's a way to introduce three important characters in the story. As I explain at the end, from this point on there's an inventory, an action menu, and a map to change locations, which will change the game mechanics and make decisions start to carry real weight, although this is already happening "invisibly" in the prologue.
