Good, but...
Its quite fun , nice style aswell and the music really fits and gives it some more fast paced feeling... but its almost impossible to dodge an obstacle if you are running 98mph, best way is just to jump all along and hope you dont hit something. Or theres just no point in speeding uo that much, always stay at 20mph or so? Cause the warning symbol shows up way too early.
It would have been much better if you added sounds when you take a battery, slow down, hit a wheel etc... And I just had the feeling that gameplay doesent run as smoothly as it should. (Maybe its just my crappy computer)
But for a first submission this is awesome... keep it up!
