I liked the puzzles with the new puzzle generator, they were markedly tougher then the first 30. I believe the larger number of separate loops did the trick.
Great game, but the fact that we are able to beat the ace scores is not nice. For eg I managed to complete lvl 78 with ace score of 56 in 33 moves. I am sure with a little more testing you should be able to figure out the optimal moves for all levels. 4/5
