R1 remains V5!
Changelog History of R1:V2 - Added OWAs to fix a backroute thanks to Crane.
V3 - Changed right OWAs to down OWAs and left OWAs to up OWAs to fix a backroute thanks to JRT.
V4 - Modified the terrain on the left side of the exit and added more steamblower traps as a result, reverted the OWAs back to V2's, and increased the Lemming count to 50 (save requirement is therefore now 48) to fix a very minor backroute thanks to Crane and Armani
V5 - Lemming count increased to 60 to fix a backroute thanks to Crane.
R2 remains V8!
Changelog History of R2:V2 - Added steel to fix a backroute thanks to Crane. edit: Reattached, as fencers are now pickups too, as a fix for a backroute Armani showed me on Discord.
V3 - Removed some steel, took out the fencer pickups, and there are now just 3 lasers again to fix backroutes thanks to Crane and Armani.
V4 - Terrain adjustments, added some terrain, and made 4 of the fencers pickups to fix backroutes thanks to Armani
V5 - All fencers are now pickups, 4 bashers have been made pickups, +1 laser, and added some fire traps to fix backroutes thanks to Armani.
edit: Reattached as I've moved the basher pickups to a different location, as I believe the old location can still cause the level to be cheesed
V6 - Reverted the lattice area back to V3's and restored the basher pickups to the original location I had before I modified V5 for that. These aren't backroute fixes but let's say some tiding up I decided to do.
V7 - Moved the basher pickups back to where I had them in V5 before I moved them again before Armani's resolve to fix a backroute thanks to Crane.
V8 - Shifted the steel near the exit, removed the steel from the top right, and -2 fencer pickups so now there's only 3 to fix backroutes thanks to Crane.
V13 of R3 uploaded!
Changelog History of R3:V2 - Extended the walkway on the bottom right area to fix a backroute thanks to Crane.
V3 - Modified the terrain and added a flamethrower trap to fix a backroute thanks to Crane
V4 - Added steel to fix a backroute thanks to Armani
V5 - Added a wooden staircase not to fix a backroute but just to introduce an element that I originally wanted to add an additional challenge/obstacle for players. If the level can be cheesed with this, then I'll just upload an update to revert the change back to V4's.
V6 - Added a flamethrower to fix a backroute thanks to JRT. Added another flamethrower as decoration and also for a bit of symmetry to the level
