Could use some work.
It was okay, and it hand potential to be awesome, but the animation is a little weird. There's too big of a margin of error, like, there's a space where you're not exactly touching the dragon, but it still counts as death. I think you should make the screen much wider. As it is right now, it's very hard to see what's coming up ahead of you. So the only way to get a high score is to go really slow.
Other than those things I mention, it was fun for a while, innovative and the music's alright.
