Thanks, that was a nice level! Slightly fewer things to try out than in the previous one, but still a lot of variability in the end.
Here are two variations for the start that use 15 skills.
In fact, Simon and Forestidia's solution can also go down to 15 skills with a little change, if you have the second digger not fall down, but platform 4 times after digging a little.
So I'm somewhat surprised I ended up being the only one to do it with 15 skills.

I'm happy to host the next round in a little while.
Not sure if the reason for fewer participants this time was NeoLemmix vs Lix, the novelty wearing off, or just the lack of a holiday break, but considering I've never used the NeoLemmix editor chances are I'll make a another Lix level. (I also thought of using existing levels, but also there my knowledge of NeoLemmix levels is currently pretty limited.)
