too twitchy

I played the original all the way through when it came out. It was a little too hard for me then, and not one of my favorites, but good enough that my fond memories made me buy it here (after having given it away years ago). Unfortunately, on new machines, the timing is just insane -- and I'm not sure why. When it was written, the use of timing-loops (cpu speed calibrated timing, which fails when the CPU gets way faster than the designers expected) should have been completely dead. Whatever the cause, I couldn't get past the column jumping part of the tutorial this time...
