Awesome! maybe gig the timing but I have no clue the overall feel. IT feels slow then enemy jumpy, strong contradiction. However that may very well be the point of the game. Without playing I can not say how it truly feels. Maybe look at reducing the margin between the two.
Beautify look, music and clip provide opposite reactions, with the music enrgizng and very fast paced kind action and the game slow and creepy. Suggest creep slower music to being fear anxiety. Environment sounds as well for same point.
May simple feed back.

Really great and interesting.
