Seems to be unfinished or something, I hear a noise when I press space, I guess the character is out of bounds or doesn't exist.

I can't play it... my character is missing..

Can't figure out how to start it/play--no instructions. I just get a scrolling background and a sprite of a dragon flies down occasionally. While writing this review, my browser opened a message box saying that the game was over and asked me to restart, which is the most interactivity I found. Please please please, don't ever have a flash game open a message box. Put it in the game window instead.

Perhaps you uploaded an older test version? Lava background is well-done, though.
