This was super cool. Really liked the retro arcade look to it. The shield color mechanic was pretty neat but might be an issue for folks with Chromatopsia. Might want to consider changing the shield pattern or shape as a secondary indicator for what shield you have up. Same with the color of the lasers from the enemies. I had trouble telling apart the blue and the green ones. I liked your freeze mechanic and I love when people spin it into a long acronym!
Great first submission to the GWJ I look forward to seeing what your team does next!
