Some slight suggestions would be a way to show your health or how many hits you have until you die. Couldn't get past the car one only because i rage out at video game cars apperently xD but you should have two dotted yellow lines to show where the roads are inbetween instead of just one. But the airplane one was quite easy and i would suggest making the rockets a bit more durable because i didnt know the red ones shot rockets until i started ignoring it. Over all nice game, pretty creative keep it up :D
