I'm not Tiana but maybe I can help as I've worked as a recruiter. There might be nothing wrong with your resume. Times are tough and maybe the companies you're targeting aren't hiring. Also, if you don't have prior industry experience you might find it more difficult as chances are that there are experienced video game pros who do have experience so you're competing against them. Your best bet? Try to network with people in the industry and get to know them. That way, they get to know you and might look beyond your resume. Good luck!
