IntroductionLemmings Retribution is an upcoming pack including original levels made by yours truly with some remade from Lemmings Revolution.
It was initially intended to be a straight remake of Lemmings Revolution until development went further and it became its own thing.
Development started on pre-V12 releases of the engine before porting everything to the new version.
Edit(26/08/23): More info about the game and a playable demo featuring 5 levels is here:
