Great, but not the real thing
First of all, I really loved the characters and the worlds, the actions where quite well explained. And even though I didn't like lemmings at all, I really liked this. The only thing that really bugged me was that you couldn't use your arrow keys to change direction. 9/10
OHO! But wait! This is not even a game, it's a demo.. And that's why it get's only 3/10. Other than that, great submission =)
