---------
I'm in favor of removing the following:
In the Countree, Edge of Oblivion, Dig This!, Bunker Hill, Land of Nightmares, Fallout Boys, Singular Squish, Case of Floating Dots
ones I'm not sure whether I'm in favor or not:
Lemming Cliche, There's a method in the Madness, I won't Say I'm in Lem, From the Brink
Other Notes:
since at least one person has solved The Shaft (part 1) the intended way of part 2, missing the gimmick entirely I suggest either altering the first one so the second's solution isn't possible or removing it.
Feel free to mention other levels that you feel for one reason or another could be removed.
