I couldn't get the tools and fire controls to work. Run makes a big movement speed difference so it may be worth making it a toggle to free up a finger. I like how the zoom goes from first-person to third-person to sim-game mode, that's really neat and not something I see very often! It's a bit early to fully tell what style you're aiming for, but I like the soothing ocean waves mixed with sci-fi drones and ray guns!
