Well a new game is always welcome in my books, even if it is a kind of copy
I can even think of a sort of story for the one lemming idea. When all the other lemmings were finding home, one lazy lemming slept in, missing the congregation. He woke up to find everyone gone and him left all alone. Now he has to find his friends again, with a bit of help from the other lemmings (the ability pickups or whatever). Help him find his way back home and to all his friends, so this story can have a happy ending
Ok maybe not the most original of stories, but come on, i just made it up then. Anyways id like to see how it comes out, keep us posted
