This must be the level that nobody wanted to review, so I'll give this one a go.
6-2: Make Mine a Large One
Lemmings: 30
Save: 25
Time: 5:00
Skills: 5 climbers, 10 floaters, 5 bombers, 2 blockers, 2 builders, 5 bashers, 5 miners, 5 diggers
Good: At least there are a few steel blocks in the way.
Bad: Even with them, it's still too easy for its position, and not a particularly enjoyable level either, even though there's not much repetition involved, and also, I could easily make this off the Lemmings level editor, as there are no unique elements (switches, acid, etc.) in this bland level.
