Welcome to the asteroids making gang! my feedback is I would put the shoot on a separate button to movement it's kinda hard to slowdown while trying to shoot.  Having a background image helps judge where you're moving too.

Nice job on submitting, I thought the game was a little disorientating, maybe zooming the camera out a bit might help, or having a border on the map boundary so we know when we're about to loop over to the other side would be cool. I thought the drift mechanic was sick, makes me wonder what a more momentum-based Asteroids game might feel like :P

Ah also when you get game over, the final score can update and increase, I think it's probably based on how the map wraps around along with the bullets still moving. Great attempt tho, had a blast playing it!! (also RIP to your 'h' key :( )
