blocks come up fast, so you can't really plan for the different combinations, and it seems to be mostly based on luck if a ground-level block appears with a mid-level block right after it, where it's too late to jump over the ground-block if you wait to see the next one, and too late to do anything about your too-early jump if you jump before it appears. going so well so far, one post.... i will try not to leave you all so long between the posts. accordingly, the trip no longer serves the educational benefit it once did. each step naturally follows the next.
