Very interesting take on the theme, and I like the concept of health being both an 'ammunition' for both shooting and moving - longer survival from more efficient and strategic movements. I really liked that aspect of it! The hit-pause was a bit jarring when there was a lot of enemies dying in a row, maybe felt a bit like it was more laggy than actual hit pausing when it happened that much, but that was a very minor nitpick. Good job! :)
