I attach my replay for V4 for All in Good Timing.

Haha yeah I just watched the video too. My R1V2 got a similar treatment, Icho doesn't like big builder levels. Now that we have the time manipulation functionality in NeoLemmix I quite enjoy the occasional chill marathon level, but I understand why most prefer much shorter levels.

The intended solution does test a few tricks with builders and management of the bashers, hence my insistence on closing all the backroutes from the second quadrant that I've been given.

When I release my level pack this will likely be placed as the boss level for the "Tricky" levels. I'm really pleased to be getting such good testing and feedback as something this size needs it.

Great Video IchoTolot!

Spoiler

I thought it might be since I would have intersected the steel that used to be there. I somehow feel I should be building over the lower pool.

UPDATE: I think you need to extend the steel a few pixels more.

I attach my modified replay.

All in Good Timing solution attached. I could save another lemming by swapping a bomber for a digger on the short pole.

Nice solution Armarni. Your second & third quadrant method is quite different from mine and saves 2 builders. I thought it was possible someone could use a builder wall over the pool. My method was the use of two worker lemmings which build towards the centre of the pool.

However, I consider any solution that has the crowd walk through each quadrant as an homage to the Penrose Steps to be intended.

With V2 I block off Armarni's backroute of MC Escher. I expect this level will be severely tested and will have many iterations.

With V3 I block off DireKrow's equally cool backroute by rotating the lower-right central OWA.

Icho Edit: Just noticed the update. Please make a new post for a new update and delete the old one, as then exactly this happens and I totally overlook it.

@Crane, Nice job solving OTAAT fast. I should study the maths behind this and see how much we can do with this taxon of level. I've already begun constructing OTAAT2 for a level pack which will be considerably larger.

Ahhh, what a beautiful backroute to my MC Escher one!

I'll submit a V2 blocking that one off later today.

Great looking levels throughout!

I attach my replay for "wrong-Side Failure".

This and "All in Good Timing" are great "old skool" aesthetic levels.

Ha, excellent. Then I just finished building my Rule One level! Finishing touches over the next week.

Hey guys, On Rule One, the symmetry applies to the terrain and steel only and objects aren't counted. I suppose this means One Way Arrows need not be symmetric? You are however able to view One Way Arrows in clear physics mode so I just wanted to check if I may have these face any direction or indeed place them anywhere.
