Here, let me describe my solution:
Considering the difficulty and tedium in doing all that just to save one more lemming, I think I'll leave that in. It doesn't take away from the level like these other backroutes do.
Is this the backroute?
That's
a backroute. It should be easily fixed by shifting a few platforms (in particular, shifting the bottom of the second holding cell up by one). Solving the level from that point should be easy.
The backroute is much more obvious than these two...
Ok, I just realized why I was missing a basher in 'Mental Blockade' at first: I assigned the bomber to some lemming in the middle (instead of the last or the first lemming), and therefore the group split up and one half went left and the other half went right at the start.
Hmm, somehow I forgot that was even possible. But since it doesn't actually cause the backroute (only lead inquisitive minds to find one, if it exists), it's not a major issue. What it might do, however, is confuse players to think the lemmings are supposed to split up like that, and make the level appear unsolvable. Seems unlikely though. *shrugs*
'Now (ab)use miners and climbers' turned into a hardcore glitch and grind fest, but it was very satisfying to finally solve it.
Oh wow, someone actually solved it. Good job
. It's not the same as my solution (which is attached, in case anyone's curious), but it's still hardcore glitchy enough for my liking
. The point of the level is getting a lemming across the top to the exit, by whatever means (which will invariably involve miner glitches). Good job working in the climber-overhang glitch as well, even I didn't manage to do that
