No this is not a new official game, it's a flash game I found:
http://jayisgames.com/games/lemmings-returns/ Has anyone played this before? Instead of using a lot of skills, you draw lines, for the Lemmings to walk on, or erase terrains with the eraser. You can actually destroy the level with it. The problem I have with this game is it's too slow and there's no fast forward. It's a lot slower than the real game, making it unbearable to play. I stopped at the second level because of this.
Has anyone played this before?
Yes. 
It's an awesome concept, but ends up being very clicky and takes extreme precision sometimes. The slowness hurts too...
Tame 1 is uncompletable as the lemmings move too slow for the given time limit. Thumbs down.
Hmm, this is also what I recall about several levels in the first game. >_>
