LIMBO is the other indie game I picked up a free code for, it’s a grayscale physics puzzle side scroller. You’re… a boy. And you’re trying to… go somewhere and not die. There’s not really any story. But the puzzles are pretty fun. I was a little annoyed that it ended when things were starting to get complex, when I thought a lot of possibilities were opened up. But there is another game, Inside, that wikipedia claims is a spiritual successor by the same people, so I added that to my wishlist.
