This is classic!
I remember playing a similar game as a kid, a sort of pixel-like racing game where you were overtaking some obstacles. It was a bit like an improved version of tetris, all B&W of course. Pretty funny feeling when you look at these computer games now and compare.
As for SNES, it's amazing. I prefer those little games to the ones we have here on PC, maybe with exceptions. I'd gladly dig up a console and play the whole evening, if I only knew in which box I hid it...
