Jumping over the z-bot was so not in Lillie's usual style that I thought I found a loophole.
Reading all the posts, seems it's the same way.
I figured out most of it quickly. (including the pink/red button dilemma) but getting the steel box to the red button was a surprisingly difficult task.
The timing for jumping over the z-bot and then killing him was easy as pie, but my fingers are good.
At the end of course I forgot to collapse the break-tile -- STUCK!

Had to strart over -- AGAIN!

Was more careful next time.
Thanks for all the fun, Lillie!
