Really interesting concept, and an endless runner that still is interesting. And i don't know if you made the graphics and music yourself, but they are both amazing.
This game unfortanetly didn't keep me playing for too long tho, and that's mainly because i think you need to press the buttons as fast as possible to fill up the health bar.
I would have prefered if you could just keep holding the buttons, but maybe that's just a personal opinion.
Also, i don't know what font you used here, but less generic and more unique fonts help the look of every game.
Other than that, pretty cool game. It would be really cool if you could check out my submission too. :)
