Cool game! Like a Need for Speed Most Wanted but in 2D.
Had a lot of fun with it!
The only thing i could critique here is I feel like your steering is inverted when driving backwards (at least if you treat it as A & D => steering Left & Right). It didn't hurt the flow anyway and I don't play too many racing games so I might be wrong.
The drifting particles look cool as well!
Well done!
