An Incident In The Mine: Your solution was unintended but acceptable. There is an easier solution though so that's probably why it felt more difficult
.
Path To The Underground: The main trick at the end is there, but the beginning with the bomber and basher was unintentional. I have already fixed this level to solve that problem.
Frozen Climbers: This one is a backroute.
Escape Route: Your solution wasn't a backroute, but being able to dig down the middle platform and build towards the one-way wall on the right is something I need to fix. Thanks for finding that.
The Abandoned Sanctuary: Don't even bother trying to solve this one. One part of the solution is hackish and I have changed it back to its original solution.
Momentum Deferred: I have plans to change the solution to this level so your solution is acceptable for right now.
We're Coming Home: Good solution, but this one is another one where I can't force the intended solution so the level is going to be changed and moved in another rank.
