v2.00 of SEB Lems is now out, this is a very sharply updated version of the pack where a vast majority of levels have gone through backroute fixes, music track swaps and sweeping changes to prepare for the new format release (I made ceiling fixes for example).
I assume this pack has now been played by the majority of forum users so I have made fixes accordingly.
I worked on fixing this pack in the old formats while making preparations for the new format conversion so there will be features that are apparent of this like ceiling fixes. I felt it was easier to do it this way.
While I have tried very hard to make sure replays are preserved, there are a handful of levels where all of the replays will be broken so
be sure to check your replays for solvability after upgrading!Apologies for any inconvenience regarding broken replays, in the majority of cases it means your solution was a back route though.
This will be the
LAST update made to the old format of SEB Lems in any case. I am now entirely moving over to the NeoLemmix new formats and I will no longer be supporting this pack in old format and will move to work on the New Format version of SEB Lems. Feel free to still report any
functionality problems with the pack but it will be my decision whether I choose to fix them or not (most likely I will if it's something quick to fix though).

v1.81m fix (still called v1.81 in the filename)
- Fixes an instance of copyright infringement on YouTube discovered by Colorful Arty, I have removed usage of inmyarms from the nxp. This track will remain in the music pack because I've just reprogrammed the nxp to not use it rather than re-distribute the entire music pack minus this file.
Please feel free to delete it if you update
v1.81 fix
- Fixes Rapture 10 which has become unsolvable due to a change I made to the Scrap Brain tileset before release. An error on my part, sorry
