This is a cool concept. It sort of combines health, ammo, and an ability into one bar, which I haven't seen before. Unfortunately, I found it a bit difficult to play because of how fast the player moved and how there was very little feedback for any of my actions (when I was hit, when my bar was below five percent, when I hit and killed enemies all would be nice to have some more feedback). I imagine quite a bit of this is just due to the time constraints of a game jam, and this could be made into something pretty unique if you're thinking about working on it more!
