After some time, here's another one:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=935184051
It's quite basic, so just for the sake of completeness

@SpielSatzFail Thanks! I added both maps to the collection, even though I didn't really like either. Too skill-based / fast reaction time / finicky jumps / deliberate obfuscation, which is saying something considering the hard NE maps I still like

I did check out the collection of the contest they came from, and I found a NE map that I did quite like called tEen lemoNs:

Also thank you for the kind words. I'm glad that Connection still is being thoroughly enjoyed after so long ^w^

Two new entries:

No Elements: Five

No Elements: Boomerang

Btw I replayed Connection after all the time and it's still great. Best in the collection imo <3

:O
IT'S A MUTONY

I always forget about this. Yep, it literally says NO ELEMENTS ^^
Too bad, it should be called "Momentum Puzzle Collection".
But wait a minute... it might be the time for...
*drumroll*
my ooown collection!
*evil laugh*

;D

I added Tier Shift to the collection. Thanks for the nice find and notifying me about it ^w^

As for the other two, while great puzzles in their own right, they are momentum puzzles, not "No Elements", I'm afraid.
The puzzle "Bonk Adjustment" especially doesn't count, since it uses a laser and flipping panels, even if the main focus is the momentum storage and management.
As for "Overfed Looparound", while the keeping in mind of fizzlers in your momentum is an interesting aspect to keep track of, it's still an element. Unless a fizzler is used to properly separate two puzzles from each other (like an intro puzzle and then the main course), it does count as an element still. Same goes for something like a lift; if it's used just like fixed stairs, I don't see why it can't be counted as "no elements". But when used for any other means, it doesn't count.
Regardless though, as I said, they're nice puzzles, so thanks for sharing at least :)

I have another three submissions, all from the same user (Aneonen)

"Tier Shift" is a simple NE map, easy difficulty, but with a tiny but crucial twist you don't see very often.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1953429970
"Bonk Adjustment" is a rather classic NE map with medium difficulty, also a little larger and convoluted, and it challenges you not to touch fizzlers but to find the exact amount of momentum.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2181068603
"Overfed Looparound" is a huge convoluted chamber that overwhelmes the player with a lot of ways and at least one hidden extra block to find. Medium to hard difficulty.

@SpielSatzFail thanks so much for keeping me informed. Sorry for taking so ungodly long to get around to playing these two most recent maps. Covid19 really put a wrench into everything for me. Anyway, I've added "All Downhill from Here" to the collection!
As for "Not so Fast", I think that one doesn't fit in NE: Expanded. It's a flinging map that people who play the tougher No Elements maps might enjoy though, as you said :)

Two new contestants (both by Libbybapa):
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1574998356
"All Downhill from Here" is a solid NE map combining different techniques: air strafing, preserving momentum, crossing the goo via angled panels. Rated 5/10 by Libbybapa.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1583124471
"Not so Fast" contains turrets, but only to force a different fling before the final fling to the exit. It requires three types of flings. The last one took me ages, so I wouldn't agree with Libby, who claims it's a 4/10; I'd say it's a 6/10 in comparison to "Downhill".
Both maps definitely built for experienced NE players :-)

@SpielSatzFail that's a neat little No Elements test chamber. Played and added to the collection :)

Here's another one - a rather short one; medium difficulty I'd say, easy if you're familiar with no elements actions. It wonderfully combines keeping your momentum via angled panels AND reshooting portals from ground floor to the ceiling. You'll see what I mean when you play it :-)

@SpielSatzFail Played and added to the collection! Thanks for notifying me :)

Here's one more: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1274638387
Medium difficulty imo :-)
Not a great one (regarding the design), but makes you think for a moment.

@SpielSatzFail Played through it and added it to the collection! Thanks so much for informing me about these more recent no elements maps :D

Here's another one :-) I couldn't recall it exactly, played it a long time ago, but now it popped up again ^^ It was a nice one too.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=952782842

@SpielSatzFail thanks very much for putting it on the radar for me. I've added it to a spot in the collection where I think it makes sense to put it, and will find the proper order for it in the collection once I can get around to playing it :)

Hey Hazellius,

I'd like to mention another candidate:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=227413169

This is a great No Elements COOP chamber <3

@SpielSatzFail Thanks for bringing up the No Elements map. It has been added to the collection :)

Thanks for the reply. The collection is in a permanent flow and I like that. It means it's alive and somebody cares :-)
I'd like to add a suggestion, a pure, rather simple, but fun no elements map.
It's this one: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=140781756
The difficulty is medium for players new to no elements, easy for the experienced. It's all about doing your math ^^

@SpielSatzFail The main reason why there are even maps after the likes of Shadow, Arc, and Supernova, is because those maps after aren't no elements maps (yet). I was going to make no elements versions of them a long time back, but life has been very busy, unfortunately. My intention is to still get around to doing that. For now though, I think they make a relatively good appendix to the collection to have the player think how the map could've worked as a No Elements version. Hopefully that makes sense

Me again. Done with all of the chambers.
A difficulty curve will always be a matter of personal experience/taste and can never be objective.
What I'd like to see is putting the ninja move maps(*) last since they are some kind of "special interest" imo and not accessible for everybody but only for skilled people :-/
The No Elements collection should generelly be executable with less exercise. Just my two cents.

(*such as Wall (remake), Simplicity, Shadow, Arc, Supernova and Hotline Fling)

Thanks for the quick clarification :-)
Too bad I started the series in the first half of 2018...but I very much appreciate giving them a difficulty curve. Thanks for your efforts. And hey, at least I was able to already overcome that pain-in-the-ass Supernova :-P
Now things can only get better! xD

@SpielSatzFail Yes they have :)
Though that being said, while the maps are arranged to have a steady difficulty curve, starting at the "Back to Basics" map, there's some breathing room with some easier maps. The difficulty then goes back up again steadily till No Elements: Supernova. The maps after that one are still a bit more all-over-the-place, because they still contain elements.

Out of pure curiosity: Has the order of the chambers been changed recently (last couple of months)? Maybe they have been rearranged in terms of difficulty? :-)

@Almisuifre thanks for bringing olshi's map to my attention. It has been added to the collection :)

Hi Hazellius, add this to the collection, olshi is back with a nice one :
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1360080837

@quaternary I'm still working through some of these maps, including easy fling and q-ty. I want to create a difficulty curve that's fair so that when you get around to the maps with unorthodox tricks, you don't feel cheated on. Thanks for the new map, looking forward to playing it ^^

add this https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=870672867 :D

also a handful of these maps are unsolvable with "normal" tricks (like easy fling and q-ty)
