The controls in this are badly thought out - you start driving to the right but have to press up arrow (= 'forwards' not 'up'), and it is not obvious which way you are facing. I died 5 times before I realised that right and left was steering, not direct control. Not very enjoyable.
Interesting idea, lots of petential, but the way the first bricks drop with no warning, and then you end game so quickly, makes the first experience a bit of a turn off. Perhaps a slower ramp up of challenge.
