I like the concept of all stats being merged into one. I think that concept has a lot of potential, especially if you try to think of how it could be implemented in genres outside of twin stick shooters. 

This was pretty fun for what it is. I really enjoy the music, and that even the tempo was tied into your overall stat. A great way to give immediate feedback into how you're doing. Its a shame that there is a controller requirement, as I feel the gameplay doesn't benefit too greatly from one. I also think that this will prevent some people from playing your game. But thankfully I do have one so I could check it out. 

What impresses me most is that you say this is HTML5 / Javascript. Did you use a framework, or is this all vanilla? I learned game dev via JS, so it has a special place in my heart :)

Nice work!

Sorry man, you cant require controller by rules of the jam :/ 

I love this take on the theme! this is a very well done bullet hell with a unique mechanic that is quite impressive. I like the scaling difficulty with player success. I would like to see it joined with a system that rewards playing well cause as is the game actually gets easier when you take damage. the art is simplistic but it's presented with style and cohesion which really makes the game look good. The number one thing this game is missing is JUICE. a bullet hell that lacks juice is like peanut butter without jelly. I would add particles, screenshake, animations, googly eyes, and just make the game feel amazing. I promise you it will be 10x as fun if you do. checkout this video for a great example of how important juice is
