Neutrality 19 - I was stuck on this level for a few days, but this solution is able to save all instead of losing 1 and doesn't even use the pit before the trap. However, to achieve this the blocker and miner have to be assigned very precisely. You can say that I kind of brute forced this level instead of what Namida did. I initially made use of the pit, but it never occurred to me to release the blocker and then reassign a blocker on the builder staircase later.
Neutrality 23 - While this uses all the tools, I was able to avoid the right side of the level completely. I initially thought about using the right side, but I thought fencing wouldn't work. Plus, I never bothered to check to see if it would work, but it does indeed work as Namida's video replay shows. This level did give me problems, but it didn't take me anywhere near as long as 19.
Neutrality 36 - Definitely a backroute! As a result, I had a disarmer leftover. Should be an easy fix, though. I did think about using two platformers on the water gap on the right side, but I never was able to get it to work so that one of them turns around. Instead, I kept using a platformer and builder, which will always turn the builder around, but a lemming going through the traps would always fall into the water before the gap was closed or even if no lemmings fell in, the other problem was the next water gap to the left of the entrance and finally some lemmings would turn around before a lemming got a chance to bomb through the wall. Due to the time limit, you can't afford to have any of them turn around before they can break through.
Neutrality 41 - This solution fails by 1 platformer!
Even if I do have another platformer to seal the gap, I then am a walker short. Therein lies the problem: I'm always a platformer or a walker short. There must be a trick that I'm missing. I know you gave Armani a hint for this level, but I absolutely refuse to read it. I've beaten your Lemmings Reunion pack without consulting any playthroughs, and I would like to do the same here. This level has stumped me for almost 4 months, and I know I could skip this and play the other levels in the pack, but I personally love playing packs in order, which means I refuse to proceed with the pack until I beat this level. With this, no hints yet, but rather you can just say if, for example, the beginning part is wrong or something else if you think this will give away too much.
