Really nice one of a game. I like how snappy movement and shooting it, maybe enemies shoot too fast, but it's more for a polish (anticipation charge before powerful attacks on enemies?).
Persoanlly not a fan of collecting powers as it comes with managing inventory on number keys, but it's not difficult to get hang of, so doable. And it should play into Combo theme as it's really great to combo guard break into sword for good damage.
Most finished and interesting game so far :D
