Pretty good. Player can shoot enemies outside their firing range, so its easy to cheese, but if you get too close they aimbot and never miss. It would be nice to make them a bit less predictable. The secrets were fun to find, not too easy. Level design is good. The guns feel awful to shoot. I think some animation work and a little screen shake/bob would fix that. Audio is decent. Pickups are decent. I would definitely play more of this. Keep going!
