ok, good news. I resolved Colorful Arty's levels that he changed. So now I have completed version 1.1 of his Artlems
ok the levels I had to resolve were
Ancient rank
level 2
The Crypt of Ramses II
This level I resolved only for the Talisman, as Arty put a steel block near top left entrance thus breaking my v1.0 replay
This level is open-ended though, so it's an easy level, even to get the Talisman.
Medieval
Level 2 Under the Flood
Arty changed the level by removing the climber pickup and added the builder pickup. Thus the solution is a little different from v1.0.
level 9 Castle Crawl
Arty changed the level by adding a steel block at the top near the entrance. Thus breaking my v1.0 replay. Solution is a little different, but much more difficult.
level 10 The Secret of the Twin Falls
Arty put 2 thin blockades at each side near entrances thus breaking my v1.0 replay. Solution a little trickier. I knew my v1.0 of this level was a backroute.
level 14 The plague took us all
Arty added 1 more zombie guarding exit so it broke my v1.0 replay
Renaissance
level 1 By Land or Sea
Arty put the tree a little higher up on yellow terrain breaking my v1.0 replay
Baroque
level 2 Summer Sting
Arty made a slight terrain change breaking my v1.0 replay
Just had to tweak my v1.0 to work for v1.1
level 3 The Fall of Autumn
Arty added a steel block and a hanging Tarantula thus making level a little harder. Broke my v1.0 replay. New solution.
Neoclassical
level 1 Median meeting
Arty added downfacing OWW's on terrain near entrance and added a blockade near right hatch thus breaking my v1.0 replay. New solution.
Romantic
level 3 A Night on Lem Mountain
Arty made the 2 cloners pickup skills thus breaking my v1.0 replay. New solution. More difficult.
Modernist
level 2 Art's Abstraction
Arty made a slight change in terrain, thus breaking my v1.0. Still similiar solution.
level 4 Blue Badge of Honour
Arty added down-facing OWW's on top-middle block, thus breaking my v1.0 replay.
Solution somewhat different, but more difficult.
level 5 Hailfire Peaks
Arty just added a Talisman to the level (nothing else changed).
I got the Talisman. Version 1.0 replay still works, but just doesn't get the Talisman.
level 6 Circus of Chaos II
Arty put some hanging blockades left of exit, thus breaking my v1.0 replay.
I already solved this level afterwards even before Arty updated the pack as I wanted to get all the pickups, since I was unhappy with my 1st backrouted replay.
level 8 Flip-flop
Arty added steel, thus making level harder. Broke my v1.0 replay. Different solution.
level 9 Castle of frightful lucidity
Arty added right-facing OWW's on block near left-bottom hatch. Also made some small terrain changes. Broke my v1.0. replay.
level 10 The Last Straw
Arty added a thin vertical blockade right of hatch, breaking my v1.0 replay.
The other levels I don't see any changes in them as my replays work still.
So now I completed v1.1 of Artlems again on my own.
ok, here are my resolved level replays.
