Voice acting?!?!? Wow!
Cool looking, with fun mechanics game and satisfiying effects on the bullets! Maybe the difficulty curve is a little high, and the boss has a little too much health, maybe its because Im terrible at shooters, like, TERRIBLE TERRIBLE at shooters, but it was fun. Another thing that you could improve is that the UI blends a little too much, like the boss's HP bar was hard to read when he was taking damage or not. Anyway, great job!
