Good work. Maybe you could cut a bit of the green off at the bottom so that it is less tall and fits on the screen better. And maybe you could allow 'space' for fire as well.

Woah, much too fast on my computer. You should put the speed slider down until it starts slowing down on your machine. Otherwise it will be too fast on faster computers. This is the best game title this week, though!

Looks interesting! I wasn't quite sure what I had to do though. I think changing direction should turn and move in one go, rather than requiring two key presses to move in another direction.
