I thought of that route for Highland 9, but I didn't have any luck trying it out. Good job!
Anyway, in honor of the World Cup, I figured I'd take a look at the Sports tribe:
Sports 3: The minimum skills solution uses 3 platformers, an attractor, and something to release the attractor. The attractor can be eliminated thanks to the large number of jumpers, which you can use to hold back the crowd. Also, the second platformer can be replaced with fillers, so I'm left with
2 platformers.Sports 4: 1 roper appears to be necessary to create a path for the crowd. Everything else is avoided quite easily.
Sports 5: The intended solution uses three stompers, a jumper, and a filler. The filler can be avoided by using the direct backroute, so this leaves
3 stompers and 1 jumper.Sports 6: ccexplore's 4-skill solution uses a fencer, a super lemming, a roper, and a platformer. The super lemming is easily avoided, and I've also eliminated the platformer and fencer in separate solutions (see hints). The result is therefore
1 roper.Sports 6 No Fencer: A platformer holds the crowd back while one lemming goes ahead. He has to platform the gap to the right of the exit and explode on the non-steel part of the ceiling over the crowd. The crowd then needs just one well-aimed roper through the exploder's crater to get to the exit.
Sports 6 No Platformer: This is quite similar to ccexplore's minimum skills solution, except that the fencer explodes at the far left edge of the level. The exploder's crater sets up a place where you can set up the crawling trick with just a roper, although you'll have to use jumpers to delay the crowd so that they stay away from the blast radius.
