Fun game! It was like a bullet-heal but instead of dodging bullets you were dodging food. I really enjoyed the concept. I especially liked how the character's sprite changed during runtime to reflect the health level, that was a nice touch.
If you wanted to improve, I suggest having the final score on the end screen, I have no idea what I finished with score wise. I would also suggest you show where people are going to spawn, most health I lost because someone spawned right on top of me. Lastly, a little more animation on the character could have helped. If you didn't want to make any more sprites, you could accomplish this by just rotating the sprite back and forth and spawn smoke particles on the feet while they move. That's the style I went with in my game and I think it worked well.
Overall fun game, it gave me some good laughs!
