i would make the camera feel less robotic, and i would add some visual cues that tell you when someone is in danger.
to make the game longer maybe some more levels or "minigames" . like grabbing all the remaining people like pikmin and transport them to another place!
about the professional voiceover i am fine with it. i just feel weird when i notice something is made with thhe help of ai xd!
would help if you check out ouur game too!
