I really enjoy game concepts like this. It would be fantastic to see you expand upond this idea. It'd also be a great idea to find a way to make it so you can make the protagonist not die throughout the game and add an additional alternate ending to your story for any player that manages it. I think this would be a great full scale game if given some polish and continued. Would love to see a full story.
