Here's "Last Lemming Standing", a level that uses pre-placed neutral lemmings. This I plan to make my "Chaos 30" level... it's not particularly hard, but intends to be an epic finale. Also, the level has a talisman. Enjoy. (The other file is the level's tune)
Remember, this level uses neutral lemmings and hence requires NeoLemmix 12.7 RC or later.
