I played Lemmings Reunion three summers back then in its initial release (V1.0) solving 148/150 first levels in the pack and I always thought of revisiting it. Now, after a loads of backroute fixes and moving to the new formats, I finally decided to play this great pack again.
There was an issue that I didn't think I have to take into account. Sadly, my replays were saved in lrb-format, and they didn't work anymore in current NeoLemmix. Fortunately Nepster provided me NeoLemmix engine that could play lrb-replays but save them in nxrp-files, that are used these days. Still, it was lots of work and some solutions were broken because of physics changes, so I needed to resolve some levels even though they virtually had the same solutions than already in the initial release. This is my fourth day of re-playing Lemmings Reunion, saving working nxrp-replays for 147 levels out of 150, that are attached to this post. Old replays not working in the new engine is a bit unfortunate, and can to some extent reduce motivation to play again old packs, that might have backroute fixes, new levels and such after the first playthrough ages ago. I'm hopeful that I won't enconter this many more times, but it might take a while when daring to have my second go at packs like namida's older Lemmings Plus packs and NepsterLems, where I saved my solutions in lrb-files.
Anyway, levels I didn't yet solve this time after a solid amount of time (I really like to move forward on to new packs):
Nightmare! 4: Stop And Go! - No idea so far.
Nightmare! 21: Rockbiter - So far my solution fails barely due to some pixels/one skill too much used/one lemming too much lost.
Nightmare! 29: Lemtris Version X - This is the level where I got stuck in 2015 and I didn't even try it again... yet.
It's a beast, yes.
The last level, Nightmare! 30 was fun even though really exhausting, I polished my solution for it for over an hour last night. I never took a look at this level before just now! Really an epic feeling pack finisher level.
Thanks for this pack as always, IchoTolot.
It's lots of fun just like I remembered! Let me know what do you think of my solutions and which are backroutes.
