Hmmm... I'm kinda the same as kaywhyn on Origami Master. I figured I was just lacking information on some Lix mechanic, because I haven't played a lot of Lix. But I really struggled to find the specific placement. Either my Lixs are too spaced apart and get sucked up or too bunched together and walk right past the springs before the exit. I even watched kaywhyn's replay, and I still can't solve it lol. Maybe a prebuilt bridge would help, but I even tried jumping ahead like you suggested to build ahead of the crowd, and it didn't seem to help too much. Would an extra spring at the bottom near the exit break the puzzle? Maybe an extra spring would help it be less unforgiving?

Jolly Roger V4: It takes more skills to turn around on that pillar that's been lowered, but it's still possible.

Teleporation Race V3: My back route is still possible, but requires another platformer and some extra fiddling with the blockers.

R2 V2: I'm not sure if this has been found yet, because I'm purposely avoiding spoilers, but, I think I broke the level again. I got tunnel vision thinking I could only dig the barrier in front of the exit, when I can just bomb it.

R3 V3: I still have many skills left over, so I don't think I've found the real solution yet.

Color Coded: Very fun level! Probably the best and hardest blockers only level I've ever played.

Bee Here For You!: My solution isn't very tidy. Since I had the resources to brute force, that's what I did lol. Fairly easy level, but fun.

Fun Teleportation Race in Space: I probably found a back route since I have a few skills left over. I feel like I get the core idea of the level though. Nice aesthetics, cool level design, nice work

I'll come back to confusion cross. Aptly named lol

Got a New Toy: Loved this one, my solution feels pretty intended. I was stumped for a long time, and was even thinking about it at work today. Glad I finally beat it

Where No Lem Has Gone Before: I solved without lasers and gliders, so I'm guessing my solution is unintended. Otherwise, the theming is great. The text being backwards on the teleporters is kinda neat. I think that's hinting which ones lead to the mirrored side and which one lead within the same side? If so, that's a very nice touch.

Lagacy Of The Waffentraeger: I'm about 50/50 on if this is intended or not, but if it is a legit route, this is a very fun level. It looks impossible, which forces you to explore. I like that If it is intended, I struggled a bit to get the lemming spacing just right to pull off the stoner/shimmy boost. Though, I could be lasering in the wrong spot or something. Love the tanks. Gives me Super Mario 3 vibes.

Lemmings vs the Jolly Roger Pirates: I'm guessing my solution is a back route, so I'll wait for a revision before saying too much, but regardless, love the pirate ship. The design gives me a Banjo Kazooie vibe, and I like it

Tensegrity: I love the visuals a lot. I always appreciate levels that do interesting things with non-custom styles. Big plus for visual appeal that also servers a function, and nice little details that are just for fun, like the slime pipe, the face, and the little moon hanging from the chain. The solution was fun to find. If I had any constructive feedback, I'd say the overhang the lemmings have to reach when they shimmy is only in reach if they grab the ridges to the end caps. That could feel a little too pixel-perfect to some people I'd imagine, but it's a very minor thing. Very good level overall, definitely my favorite submission visually.

Brick or Treat: I loved this solution. I don't play with zombies often, so me figuring out their mechanics was a nice bonus challenge. They also add to the theming

A-MAZE-ING Brick House Evacuation: I like this one visually as well. It's probably my favorite puzzle out of the three I completed. I've always liked this quirky basher trick, but this level is probably the tidiest set up for that trick I've seen. Nice work Figuring out where to save skills and which path to take was a lot of fun. The swimmers were either a very good red herring, or the solution I found was a back route. I spent a lot of time trying to figure out how to make use of my swimmers lol.

The Amazing Lemming Tightrope Act: I'll need to come back to it :/    Good visually, but I spent all my puzzle solving juice for the day lol.
