Progress seems to come in bursts. I stop for a while, then pick right up again. This implies that I might stop right before 3-1, then go halfway through 3-3, then one more months of break before I finish at last.
Well, it is a pattern, anyway.
Regardless,
I'm on my way through 2-2, and currently hit with a bit of frustration at the yeti. You see, I can
leave the yeti in this fashion just fine, shooting downward to gain the necessary height to leap over the bullet. However, there is a potential to
abuse a poor KGB guy to duck under that bullet instead. This, naturally, lets me jump up to those platforms sooner (
about 14 frames) and is far more stylish to boot.
Sadly, any RNG abuse I can come up with without wasting frames hasn't produced good results, but I've come close a few times. I may simply continue if I can't reach the optimal solution in this run.
