Hi Ethan,
I loved the demo and was surprised that I could shoot throwing axes and break doors while sprinting. It's good that you didn't add any tutorials. It's better to experience those details and find them out yourself. You can add features like stunning the enemies after you sprint past them, or being able to play shield only, just like the type of enemy with only a shield. Also, you might want to add some text to the books lying around. Perhaps some Bible quotes, or better yet, your own mythology. It'd make the world more immersive if we could read the books.
By the way, I am an official Turkish translator. I can help out with the localization, if you want to add Turkish.
Best.
