Indeed, in all instances I remember, putting either traps or terrain somewhere over the exit works to prevent backroutes. But if we decide to stick to that, then the current options are sufficient and we don't need an alternative exit&trap object. Mixing the exit&trap object option and the usual exit&terrain option would only make the downside "usual exit = direct drop works" more serious.
IMO the whole point of (optionally) disabling direct drops is to replace such (sometimes non-reliable) case-by-case modifications with terrain pieces or traps by one universal change in the game mechanics.

Instead of stalling outright, you could alternatively shorten the cycle, skipping the "trying to move forward part" and immediate make the basher start another stroke, whenever it gets into a situation where there's "sufficient" amount of terrain in front of where's he's moving into.

Good idea, but I would replace the "whenever" part by "whenever the basher was turned around by a blocker".

With Simon's mechanics, there might be some ways to exploit the ability to move into terrain:
- On a terrain which rises only very slightly, the basher usually stops after one stroke. However one could now use blockers to move the basher into terrain, which enables the player to start a permanent basher.
- Depending on the precise mechanics the following may work: Move the basher into the terrain and then change her to a digger. This might separate her from the rest of the Lix.
- Moving into terrain could be used to create deeper bomber holes, cuber-boxes that can be stepped upon by other Lix, ...

Solutions for updated levels (except for "Parking Garage", where my first solution should still work).

Just to clarify the confusion with the Lix versions: There are two very different solutions that I know of.
- One requires the old basher/miner/digger-mechanics and will certainly not work in 2015-08-09. However it should be robust enough to work in any of the other versions (though I only checked it with 2015-06-08).
- The other solution is independent of the precise basher/miner/digger-mechanics and should does work as well in 2015-08-09. I haven't had time to confirm this yet, but will do so this evening.

EDIT: Solvability of Altruism with 2015-08-09 confirmed.

Electroshock V4: Builder replaced by platformer and several slight terrain changes.

Thanks, but still a backroute. V3 is on the way.

Nobody else underlines.

I was deliberately copying the style of namida's previous two rounds, because I did not want people to start comparing styles of various Family Feud rounds to exclude possible hosts! Guess it didn't quite work as intended .

That seemed to have worked quite well except for #14, for which I wonder how many people inadvertently burned me by going for the intercardinals?

Only one. Three people just answered north.
