If I'm not wrong, one big difference between the old NeoLemmix Player and Lix is that Lix comes with level packs and graphics etc. whereas old NeoLemmix relied on the level packs that come externally.
The new format has separate files for graphics etc. as well. And the styles you have to download separately, which I think is more user unfriendly (than in Lix where everything is included) since you often need them anyways.
That's actually the downside of having separate files for graphics etc. that you have to carry and update them through the instances as a player as opposed to everything is in one file. But I really don't want to speak against the Lix or the new NeoLemmix format. I think it's good that you can have a view inside the files and change them if necessary.

I can't say anything about the (NeoLemmix) editor and the upgrading system to what GigaLem probably alluded. But in Lix the editor is integrated, which is more user friendly I think as well. So an upgrade system would probably apply to the whole Lix release and not only the editor, I can't say how viable that is.

It's probably good to point the player to copying the old config.txt and data/user/ in the new instance to retain configuration since this is not obvious.

In view of that Clammings has "Urban Ledge-End" (ULE) in Insane (probably with other intended solution though) don't we want to swap it with "Inside the Forth Wall" (ItFW) as I suggested earlier?
Or does anyone has problems with ItFW but not with ULE?
Due to removal of trampolines ItFW is not in its original version, maybe that makes it easier but for me it was a huge contrast to the other Insane levels.
Or does anyone think ULE is in its current version too easy for Insane?

Attached replays to both showcase levels.
The Raymanni-level-replay should have the level data compatible to Simon's zipfolder. Some things were out of place for some reason, so I tried to fix that but I'm not sure if I got everything.

The screws are earth. Do they look like steel?

You maybe shouldn't have asked that beforehand, since it is then hard to have an unbiased view. But I actually think they are dark enough to not look like steel.

I'm a bit late with saying that but since you're intersted in the assessment of difficulty and enjoyability:

I wish a good and healthy end and start of the year to everybody and the people that are dear to you.

I won't be away over the end of the year but I assume many will.
From February on next year I won't be probably that active anymore since I really have to take on real life.
I'm actually afraid if I can make it but I have to try it.

Thanks Raymanni, looks really nice.

I have played through all of Perplexing (as of 0.9.4) and attached the replays. "Division Compromise" unfortunately got a 5min-replay. For the one in the zipfolder I deliberately delayed the last action, so that it completely verifies but I've attached my original 5min-replay as well.
The beginning levels were only a soft rise in difficulty but then it got harder and sometimes very trick oriented, sometimes very out of the box. The levels generally seemed more to the point with a more tailored skill set.
The levels were generally enjoyable and interesting as well.
