My fiance' bought it for me from Steam tonight. The video they had looked alot like Lemmings(big surprise, right?) and I always loved that game. So we took a chance, and I must say, it's a LOT of fun! It's the kind of game that is relaxing, while making you think.
Needless to say, I'm still learning the game, but my handle here is the same as my Steam name. If anyone wants to play MP mode, add me as a friend, and hit me up.
