Gronkling found a second backroute that left him with just 8 seconds on the clock.  I quite like this one actually, although it unfortunately got fixed in my latest version of the level!

Thanatos Gambit:

- Pieuw - backroute (v0)
- Akseli - backroute (v0), backroute (v1), backroute (v2), backroute (v3), backroute (v4)
- Gronkling - glitch (v0), glitch (v1), backroute (v2), backroute * 2 (v3), backroute * 2 (v4)
- möbius - backroute (v0)
- Clam Spammer - backroute (v2)

Hopefully this answers all the backroutes to date... emphasis on hopefully!

Gronkling found another pretty good backroute in the same version, but isn't too far from the intended solution in places.  I still haven't completed Gronkling's level yet - wow that is hard!

Thanatos Gambit:

- Pieuw - backroute (v0)
- Akseli - backroute (v0), backroute (v1), backroute (v2), backroute (v3)

- möbius - backroute (v0)

Find attached version 5 (numbered 4, since I started at 0)

Frenzy 27 is actually a backroute, but because of its beauty, and the fact you have to make sure it's the Climber that does the final building (otherwise he climbs the barricade on the far right and dies), I'll give it to you and let it stay!  It's actually impossible to do it this way in Lemmini because the fire traps are less forgiving, but I do love your solution.

Well, no more submissions for now, so I gather players haven't found any more backroutes yet.  Hopefully that means I can release the next version with everything patched.

Sorry, I wasn't aware of the Lemmix player - I guess I need to look around more closely.

Heh, I'm having problems opening the correct level because it says it can't find graphic set 6 (I'm opening level021.dat which contains the correct level).  Can anyone give me some tips so it recognises the Oh No! More Lemmings graphics sets?

Oh, and I've found that "Sharing a Climber?" is impossible to complete on the Lemmix version due to the aforementioned steel problems.

ADDITIONAL: Can someone check "The Final Countdown" (Picnic 30) too? I'm having problems with the steel areas and the splat distance (a digger in the right place survives in CustLemm and Lemmini, but splats in Lemmix).

That'll be one of my levels!  This level was originally made in LemEdit and designed for CustLemm, so it should be doable in Lemmix.

You have to get two lemmings to build towards each other across the expanse in such a way that the lemming coming from the right turns around (by hitting the other builder's bridge) and heads straight for the exit.  You are also correct that you have to stop the climber from climbing the left pillar.

I hope I didn't change it too much to the point that it's a different level.  I was trying to patch backroutes while keeping the level pretty and also keeping the intended solution mostly the same (some positioning has changed slightly).
