The game is fun, great visuals too! The shooting feels punchy, but I think you should use another method because it's fairly obvious that it's freezing the game on each shot. Fuel should probably move slowly towards the player or center of the screen over time, so you don't have to scrap the edges where you'll probably run into an offscreen enemy.
