First of all great job with the game! I had fun playing it.
The main menu is really nice and the music as well.
I found myself trying to rotate the camera at points.
Feedback on when you get damaged or a health bar would have been nice, I didn't realize when I got killed.
The mechanic was a really nice take on the theme but I would have liked it if it had more repercussions in the game. Integrating it with the gameplay in more ways would be hard to do I imagine but really fun.
