Fun game. I enjoy the simplicity of it. A couple of things though. The controls for the desktop weren't immediately intuitive. I tried the usual wasd or arrow keys to move, and even moving the mouse. It was by chance that I figured out I needed to hold down the left mouse button and move the cursor to dodge the asteroids.
I also think it'd be cool if you could destroy the asteroids by shooting them or something if you had enough power rods (maybe an energy meter that runs down with each shot but fills back up when you collect a power rod).
All in all, it's a simple and fun game. I love the movement of the rocket and how you can really control its lateral speed.
