Oof, first of all, I love your lighting, it adds so much to the gameplay!
My internet sucks so I couldnt download the file, but I watched your walkthrough! Another thing I like its your sound design, well done there! plus the camera movement feels so smooth and works perfectly for the game! I would like to know more about the story and universe of the game, so maybe you could think about adding some cinematics explaining the story?
Great work :D
