This has potential. Not so much a fan of the tank controls though, but doesn't put me off from it completely either. I laughed a bit when all the NPCs were talking about the world ending and all the death and carnage, and the music in the background was bright and cheery. I would say, it needs more art direction. Right now it looks like a mishmash of different assets conveying different styles, but I understand there probably wasn't enough time for you to make everything look cohesive. Still, impressive work and congrats on submitting!
