I can feel Wolfenstein from this, I liked sourounding music and maze like nature of levels. What I didn't like was starting from the beginning when dying. And if I am not mistaken shooting enemies don't make sound? I was at the beginning of the level just sipping my tea seeing melee enemies don't do anything and then I realized I am almost dead because shooting enemies are shooting at me. That means readability of enemies or situation you as a player are in should be improved, same comes for damage taken. Damage done to enemies is fine, just damage taken from them should be felt more :) Nice game :) Oh and the story progression between levels is very nice too :)
