I have seen some of the comments saying the puzzle is impossible. I didn't try it as, it did look quite hard i'm sure that's the challenge in it. I was going to attempt it but, my let's play was getting long. The game itself is fun. I enjoyed you played as, an alien race or, so i'm guessing as, the other races are of some galaxy like material. I think that's an interesting concept instead of just being human all the time.
