Yer, keep your highest block in the bottom right corner then try and get the above column to decrease in size, so it would begin 16, 8, 4, 2 and so on. Then you can collapse then down onto the bottom block and repeate. Always try and keep 4 blocks in the righthand column so you're not jumping your highest block about. Try to only move down and right, only move up when forced too and move back down immediately. Never move left if you can.
