So, with the remaining 6 Vicious levels I'm pretty much stuck. Some feel close to the solution, some not.
Gr8 Escape - still not seeing how to apply any tricks with bridges to either stall several lix in 1 go (without needing an extra basher) or turn around without a wall.
Burridan's lix - 1 short on the solution for the left, not even close with the right.
100% Built - not seeing how to save a bridge on either side.
On the RHS I can see that 6 bridges are needed for the height leaving 1 bridge to both stall the remaining lix and unstall them, doesn't seem possible? But on the LHS I'm not seeing how to use fewer bridges either, 1 splatform, 2 to get past the sanctuary either side, leaves 1 bridge to allow all lix to get to the sanctuary after the first pass - also seems impossible? Obviously one of those things is possible though.
Wait Why Is there a Tree? -
Thoughts are to try to use the diggers together with 1 implode to turn a climber round and bridge right to left, but I can't see how to do that and then be able to get across to the sanctuary? I have tried sending 3 climbers up, having 1 dig immediately, the second dig into an alcove to allow the 3rd to turn, then implode the second, but can't get the timings to work - for the second climber to dig far enough for the 3rd to turn around, the imploder then ends up too deep.
Theresa Falls Up the Stairs - 2 different unsuccessful methods attached.
I can't optimise the digging any more for the platforms to reach with the second method, leading me to think the first is closer to the solution. If I can just get a lix to the sanctuary area from the start without using a batter, blocker, or both jumpers then I can solve it I think.
Chasm - Most of my attempts are variants of the attached.
I have also tried using a climber from the right trapdoor to jump the chasm from that side, aiming to mine down to the LHS - with no success
Hints for any or all would be appreciated at this stage.
