i've managed to sort of get through, minus a few coins tho
i've been using an ice cube for the blue button and an ice cube for the red button, it was the boxes i've had the biggest trouble with
now i know you can use the cannon, i'll have another go when i get the time
eta phew, used the boulder to destroy the boxes and then sent it back round, dunno why that didn't occur to me earlier
that was a real challenge.
