Boxed In - attached two solutions(top route/bottom route) Each of them are equally difficult imo but one of them spares some skills.
Crag David - basically same solution, I just realize that one builder is enough to catch the crowd hence I was able to save one additional builder than before.
Down the tube - I bet this is intended... But I've been wrong so many times before..
Drigting Away - used all skills and save some more than required. The final digger trick right next to the blocker to avoid the blocker's trigger area is quite advanced trick.
Grasping at Straws - The first solution is painfully trivial. I have no idea why this is not the first solution I found. It seems like we both missed this obvious possibility
Second solution is a lot better though.
Joint Construction - This also feels good.
Pain Factory - A lot more challenging than before. My solution spares quite a lot of skills though.
