At least he was generous with the # of builders for "Water Cascade"!
Hmm, that level didn't make me want to go off on a rant at all, even though it took a good number of tries. There's really nothing cheap about the level.
If something works sometimes (the stair trick, as you claim), you should think about why that is. In this case, it is easy to control. Just make sure the lemming who digs does so at the very last pixel on the previous step, then builds right away. This won't fail you. All the times I lost on that level were from stupid errors on my part.
EDIT: Conway, your links aren't working.
Levipak2 - Level 9: No world without you
2 Lems
100% to save
RR: 99
Time: 1 minute
Skills: 1 climber, 2 builders, 4 bashers, 1 digger
Good: Well, I don't know...
Bad: It's basically identical to the original "No world without you", except you get 2 less builders. Still, very easy. Should probably be much earlier in the pack.
