Little update:- The zip now has the standard levels/Pack structure inside so that you can simply unzip it in the main NL folder.
- 2 updates regarding 2 of Turrican's levels: "Outside the Control Room" and "Dockside warehouse"
For mantha's feedback:level 7 im already stuck so Im not sure if the rank difficulties will match what I think easy should be.
...
figured out 7
8 is a really good puzzle but def not easy imho
The pack will 100% not match the definition of "easy" for most people. It is nearly impossible to hit that.
But, as you can see rank 1 has not that many entries yet and I admit that the majority of the entries hit what I would call the "second half" of the first rank where the levels have gotten a bit more difficult already.
Therefore I look forward to more rank 1 entries for the "first half" where things should be quite simple for the vast majority of players! 
The fact that in the same hour after the stuck post you posted that you figured it out would confirm to me that around "midpoint" to "second half" of the first rank would be an acceptableplacement for example. At least roughly and of course difficulty arrangements are also totally up to debate. I think we should first fill in the rank a bit more though.
Also, for the very first few levels in rank 1, I plan to take the visual aspect heavily into account as the first few levels should be looking quite nicely.
also unless I missed a trick which is entirely possible its everything Ive seen people criticise other levels for in terms of a buildery fest which is fine if its the only one which it could well be
I
personally would be willing to have some selected builder-heavy levels in the first rank as it can be a good training.
But definitly not many! Also the ones we have should be at least somewhat interesting and visually pleasing.
This can be up to debate though!
