You've done a very good job of making a groundhog day/edge of tomorrow style action story! I think one of the best choices you made with the story is making the main characters a band of scavengers stuck in the middle of two larger forces. It's a small but deliberate choice, and I think it adds a lot to story- I do wish you did a little bit more with it, because that's such an interesting idea. It just seems that aside from one point, only the robotic legion has an effect on the rats. I understand 1k is so little time, but you made such an interesting choice by making the main characters third party scavengers I do wish you could have played around with it more!
