I solved all Cunning levels of the lemforum pack (as of v. 0.9.1) and attached the replays. 35 were done in 0.9.1 the other 5 in 0.6.36. I checked the older replays with 0.9.1 and they should work there. For "Lix Cannon" I happen to have two (quite similiar) solutions.
I played it mainly on my old laptop, so bigger levels were a bit laggy, which had its advantageous sides but also made certain sections more tedious. But that's my fault for using outdated technology there.
It was sometimes quite rough for me. On some occasions it had to do with finding the approach, on other it was the precision required and on some there was much to deal with at once. Some levels really seemed to require advanced knowledge of the game. But in total it was an interesting task to perform for me. Thanks for making these levels.
Some remarks on some of the levels:
I noticed generally that a often used trick was the exploder-on-the-wall that creates extra ground to work with.
I liked in "Under the Rainbow" that my attention was focused on the lower route but in fact I was sucessful with the upper route.
I really liked the "Tapestry" level, which had a nice puzzle.
Labyrinth of Persia has a plus with me because of the allusion. I really love the DOS Prince of Persias.
"A Soulful Bounding Leap!" was the level I solved last and was with "Seven Pillars of Lixdom" the levels that I had most problems in finding approaches.
"Don't look back" was a nice short level.
"Once You Pop, You Can't Stop!" felt a bit random to me though it is probably fully controlable.
In "Some Like to Run" I found the use of runner a bit strange since it mostly waited.
"Compression Method 2" was with "Mice in the Pipeline" one of these levels that have an interesting idea in using game mechanics but overdo it in the implementation in my opinion. Both replays are lenghty and I seemingly do nothing but I either missed the point or had to wait. Fortunately they are rather lenient with the amount of lix to save though in "Mice in the Pipeline" I had the ambition to save all the climbers.
I like the Little Miner Puzzles since I like having different tasks in similiar levels because I have already thought myself into the puzzle setting.
"Buy One Get One Free" had actually a nice puzzle but I didn't know the quirks of the cuber at that time so I had to learn it there the "hard way".
"Well OK then" was a strange funny level.
"Jacob's Ladder" and "Dr Strangelix" were the levels that I had trouble with overseeing all the actions. They were very busy.
For "Walk the Plank" I didn't plan for the second climber to make it that close.
