Tom andy It took me a surprisingly long time. I thought it would be trivial and was planning to add more obstacles.
andy I tried a number of different techniques before finding something that worked. I'm glad you did find a way to do it with a little nudge @Tom - I tried various ways without success :-) I think this is the coolest level so far.
