After reading your notes I realized I found an alternate/ much less annoying solution to Watch Ye Step!:
>>>set release rate to 99. let 5 lemmings go then block. the five will go and 4 sacrifice themselves in the trap for the fifth. Make the fifth climber and let him go all the way to near the exit. Then dig, build to turn around and mine down so the miner tunnel is near the corner of the terrain near the traps then bash so he's bashing away the top of the floor. Let him go all the way to the left to free everybody else. He will die. You loose 5, the maximum I think. But the save requirement didn't really "help" me because 45. 90% seemed like a arbitrary requirement.
Can I remake this level for Lix? I really liked it a lot.
-------
for Why can't they just run, I 90% sure it can be saved using a stuck climber, I basically almost did it, I just need to work out the fine details.
-set RR to 50~60. Ignore the top section.
-lem 1 bashes then quickly builds to bash only a sliver in the pipe. he turns around and make him build left.
-lem 2 walks up into the sliver--make him build, he then turns around and do the same
-lem 3 walks into the sliver--make him build & he gets stuck. Make him climber. He'll begin climbing up inside the pipe.
-at this point the left facing builders are usually almost done, continue to build them so they hit the ceiling and turn around.
-lem 4 has to build in the sliver to continue making the hole smaller and build when he turns around
build him also.
-get lem 5 stuck once more then make him a climber also.
-have lem 6 bash through the pipe and raise the RR to 99
-the first stuck lemming should be near the top now and make him bash to the right when he's close enough to the top to open it up. Make him a builder fairly soon to stop.
-have the second stuck climber bash a little lower to open up the bottom and free the top. She should stop bashing when he falls.
-all the lemmings should have a clear path to the exit. All the other builders should hit the ceiling soon.
[In Lemmini, it takes more builders to make the hole smaller for the climbers. (Because the basher makes a larger hole before you can stop him). But I liked using that anyway because you have directional selection to select the climber going up. You
have to bash to the right]
I'm curious what your solution is Clam
