I am not sure about the movement paradigm, I expected it work like a TPS and then an FPS when aiming. Instead I couldn't figure out how to dodge and move where I wanted, I feel like the camera and WASD were clashing and fighting each other. I think making this just a straight TPS would clean a lot of that up and make dodging and shooting more fun. I dig the vibe you are going for here and I like the power ups.
