This game has an immense potential! The concept is just so creative and fitting to the theme!
But here maybe a few improvements:
I know the theme was "out of control" and the player controller in this game fits really well to this theme, although it really isn't as fun as with normal controls (that's just my opinion). Since you already have that with the shooting, it wouldn't be out of the theme without those controls.
Then add more feedback to the player, I want to feel that juice when I hit an enemy, you know what I mean? It's the same thing for getting damage, at the moment I don't feel the pain!
If you simply add a little camera shake here and there the game would feel so much more alive.
But don't take me wrong, this game is awesome and I had quite fun playing it! The things I wrote above, were my only issues. Keep up the great work!
