There'll probably be a new lix update within the next few days, which will feature, among other things, setting a minimum spawn interval (maximum RR), and lix only check against water with their feet, not eyes (this will solve the issue in Under the Rainbow).
Furthermore, it'll include some additions to the terrain: the abstract set, and the additional pieces by thick molasses and Nortaneous. (I renamed/moved them around a bit though. Only three levels are affected by it, I'll add Torture Chamber and Under the Rainbow to the list then with the new terrain location, and post the adapted version of Four Lix and a Funeral in this topic.) There'll be some smaller terrain additions in some sets, and whatever else I'll manage to get done in the meantime.
Once the update is out, I'll update the list.
I got a bunch of new solutions. Some notes:
Alternative solution to Ascending and Descending that doesn't use the builder barrier at the top (very technical solution though).
Five for Fighting was pretty difficult, not sure whether my solution is a backroute as it leaves a climber and a floater.
Cry for me version 2: similar solution still works.
My solution to Excavation uses a digger to get through the blue shovel, feels a bit technical to use a digger for this purpose.
Snowjump: another pretty technical solution.
Ridiculous: I think my solution can be optimized to a lose 1 solution.
Proc Man: My solution only works if the minimum RR is 1.
Stairs Bro: Went along right under the buzzsaws. Apt title.
Infrastructure: Love this level, only have to take care not to bash from too high.
And I updated Recycling plant to have a miner instead of a basher, I like it better that way.
