I've been very busy level making for lix (even though Simon's real reason for lix is based on multiplayer) it's still a beautiful lemmings clone to play single player in, and having the extra L2 skills such as jumper, walker , platformer, it gives you such a huge ideabase for puzzles, that I'm having a blast.
Currently I have 93 singleplayer maps made across 4 difficulty sets, like Lemmings. It 'may' get released with lix, unless Simon wants to keep the game multiplayer based. Its his call though, but either way, I enjoy my time building some pretty awesome puzzles
This keeps me away from getting back into World of warcraft.
