Completed 8 again on a different difficulty and had no problem; the disparity between easy and medium is huge. You get hurt so little and it takes so few bombs to destroy a roadblock, that you can just zip from roadblock to roadblock without blowing much up. I completed easy in four minutes with 1 crash (which was really just to save time) whereas medium took me nearly the full amount of time.
