Liked the switch to out of the box thinking in the final level.
I would too if I could figure it out xp
managed to get the robot down but the boxed gal always ends up on the wrong side.
Put the 2 slower characters at the exit first then lure a robot to open for you ? Not sure what you're missing
Can't you only "lure" a robot by getting it to sit on the top of the box-girl's hit box then scrape it off on the ceiling of the cubby hole at the left. one of the girls has to stay behind to hold it open anyway.
I used the robot at the very top of the level, taking it on the same path as you take.
