First I thought it is too slow. Then I realized it is ment to bee slow. Great work! With some balancing it could be a challenging fun little game! 

Such a cute little game, and such a fun twin stick style! I'd love to see a little more to it, maybe like a local score system as it really gives me an old-school arcade vibe, as well as some additional sound effects for various interactions, other than that, great job!

Like the other commenters, I felt like the game could be a little more challenging. I really liked the particle effect when you kill an enemy, though, it's very satisfying. Good job!

Hi! I agree with some of the other comments that the game was really easy. There was no point where I had low health, and when I intentionally took damage to see how fast I could go it still felt slow. I think speeding up the gameplay would be an important improvement. I also would like there to be more to explore in the level or a more structured and linear set of levels to beat. 

Cool concept with using your HP as an attack. The game felt a little easy though. I found I was picking up more health than using.

I wish there was more to it. Maybe if you spent more time on it, it would have been better.

It's good. Maybe you should add a score.
