Nice idea!

This can already (sort of) be done. The pack author can add a Postview text screen to the final level of the final group, which can be used to congratulate the player on completing the pack (e.g. Mayhem 30 Rendezvous at the Mountain contains such a screen!)

However, that doesn't account for when players might complete the levels in a different order; a likely scenario, since incomplete levels may occur earlier than the last level in the pack, and the player will then come back to those levels later.

So, OK then: let's detect if the level just solved is part of a pack, and ask for the completion status of all other levels in that pack. If all are solved, regardless of ordering, let's show a simple 'Congratulations!' screen.

I've added this one to the to-do list.

You might have to wait until the pack's release for the exact details but I can give you a few hints :

Spoiler

Almost everything you see in the video is not what it actually seems.

I created a special tileset(currently named armani_special - to be changed) that will be used in certain special levels of this pack, like this one. There will likely be one special level every 2 or 3 tribes depending how often my creativity sparks. By special levels, I mean they play out very differently from the usual guide enough Lemmings to the exit style of gameplay. Here's a sneak peek of an example special level that I previously shared on Discord:

Spoiler

(it's a GIF, click it if it doesn't auto play)
you have to survive long enough for the big laser gun to shoot down the boss, after which the exit will appear along with a victory message in the center of the screen

The tileset is packed with objects featuring deceptive sprites and animations; teleporter objects that use the bomber animation, as well as terrain hallucinations, walking Lemmings, gliding Lemmings and even some icons and UIs. I also made single-use trap objects with the sprites, sounds, and animations of various Lemming actions, which switch to another deceptive sprite once triggered.

The video doesn't show the ugly part of the level where the things actually happen; where it counts how many targets you've shot and triggers the hidden script. Once you see the full map, it'll be easier to grasp how it all works.

You won't have a lot of freedom in deciding what to do in the level, though. It isn't going to play like, say, Counter-Strike, but rather as you mentioned, more like Duck-Hunt X Lemmings! As for the interface used to add a lemming in the middle of gameplay, that's not possible in curent NL. I added a debug mode to my custom build that lets me spawn new lemmings during gameplay, get any amount of skills, add/destroy terrain with the mouse etc, to make playtesting levels easier.

Ok then, ample interest so far 

Some have suggested November so let's aim for that to accommodate, work wise for me I can do any weekend but would prefer the weekend of 14/15 Nov because I'm on early shifts the week leading up to it and then on late shifts the following week so it would have the maximum time between the 2 weeks of shifts (finish early Fri and start late Mon). It doesn't mean the other weekends are off limits though, that's just the weekend I prefer out of the Nov weekends.

To bring the topic up to speed, there has been some organising in DMs on Discord. I'll most likely be giving Kingshadow a lift from Rotherham to Bristol and back and we'll book into the same hotel. We can let you know what hotel we're booking into when we book if you're interested in joining us in the evening(s) to have rooms in the same hotel for activities. Kingshadow is possibly bringing a board game and I'm bringing my Nintendo Switch 2.
Also I have offered to pick up hrb264 on the way to the meetup if she needs me to, she has advised me that she'll most likely stay with her sister who lives in Bristol.

One thing that hasn't been commented on is, are we doing a 2 day (Sat/Sun) or 3 day meet up (Sat/Sun/Mon)? I don't mind which personally and I wouldn't mind opting for the 3 day if there's interest.

Quote from: WillLem on August 28, 2026, 05:26:45 AMI'm definitely up for Bristol, and would also be happy to travel to anywhere on the coast. Seaside in Winter can be very beautiful.

Where on the coast were you thinking of? Perhaps if this was a 3 day meet up, we could possibly realistically do this.

Quote from: hrb264 on August 30, 2026, 06:46:53 AMNovember would work! Let me see if my gf and/or my sister and her family would like to come, what dates you looking at?

I've suggested above weekend of 14/15 Nov since no one expressed any preference except November, but I'm open to the other weekends in Nov also.

Your girlfriend and your sister's family are more than welcome if they want to join us, whatever works for you 

Not sure if this helps in any way but if we all booked into a hotel nearby your sister's place in Bristol, would that help your plans in any way?

That's so cool, thanks for the info. If you have any additional feedback lemme know then I'll have more to talk about in the first section!
And thanks again for all the support! 

I should be available to meetup.

A level pack complete screen would be nice, as i keep replaying earlier levels, without realizing that i completed a level pack, as they just loop over.

I'd love another meetup!

Bristol sounds good for me, and November should be fine!

August 28, 2026 stream is over and I managed to solve 10 more levels of the Planet rank, one of which was Altruism, the level that Simon skipped Replays attached

I also attempted Planet 13 - Choir of the Mad but was a no solve. I remember this level from Nepster's Return of the Tribes, the L2 level pack for Old Formats NL that Nepster never finished making, so it was just a matter of remembering the solution. There, it's remade in the L2 Medieval tileset. I wasn't able to remember the entire solution during the stream before I ended. I remember it involved some really clever use of the blocker, but what that is, I can't yet remember. The interesting thing is that I played through all the levels of the pack that Nepster made for Return of the Tribes last year. So, I apparently can remember solutions from 3-5 years ago but not from a year ago? It sure boggles the mind! At the same time, there's more, and that is I haven't spent anywhere near as much time on the Return of the Tribes levels as NepsterLems despite how the levels in the former are just as hard, if not harder, and it does feel a lot harder IMO.

Once I manage to solve Planet 13 offline I'll stream more of the pack. Still haven't figured it out yet, but I know the solution will come to me given time

This time, the ones that look like backroutes are Tomb Raider and Cubism. At least I'm certain I don't recall solving Tomb Raider from NepsterLems like the way I did the NepsterLix version. I remember not taking a shortcut at all for the level in the NepsterLems pack and taking the long way around pretty much the entire level.

Both Altruism and Cubism were new to me, as they're not in NepsterLems. The rest of the levels I've played are from NepsterLems, so it was more or less a matter of trying to remember the solution I used in the latter. I remembered the solution to Five do not Survive incorrectly for a few minutes before it came back to my memory. I might had also been wrong about using an RR timing based solution in the NepsterLems version of the level. Any levels where I did abuse the RR manipulation in NL I had to come up with a somewhat new solution, though luckily they didn't need too much of a tweak from the solution I used.

Regarding Altruism, yes, absolutely agree that it's too difficult for its position. It really reminds me of Scrap the Builders from NepsterLems, and IIRC that level is Sun 7 in the latter, which is the rank after Planet and hence the 4th rank. Indeed, Altruism greatly resembles the layout of Scrap the Builders, and the feedback given for the latter is that it really feels more of a Black Hole rank level, and I absolutely agree there! Especially as both Icho and namida struggled with it. I did as well, and that was the next level of the pack that caused me to quit the NepsterLems pack for a while back in 2020, after I was finally successful in getting past my previous roadblock, Planet 13 - 50% is not Enough. Ultimately, when I finally did return to the NL pack, I ended up using a really overcomplicated solution that just barely works thanks to the fast triggering needles trap of the L1 Pillar set. Also, Altruism feels way harder than the NepsterLems version of the level!

Enjoying the pack as usual and can't wait to play the rest! Great levels I remember them being, especially the new ones I haven't played because they're not in NepsterLems      

November would work! Let me see if my gf and/or my sister and her family would like to come, what dates you looking at?

Eesh

Of course, the event handler to use is 'Change', not 'Click'. The UI should not update every time the treeview is clicked, only when a node changes.

This removes the need to track the last-clicked node, and complements the other fixes (re-entry prevention, decoupling of loading from event handler).
