I am on the last level, the Shub Niggurath's Pit. I found the secret area, into the slip gate there, which brings me back to the first slip gate around the pool. Then what? By entering the first slip gate, sometimes I get the Congratulations, sometimes just transports me into the pool. Is it a random process or is there something I must do to trigger the win?
Second, what is the pointed ball doing? I mean the pointed shaped thing that wander around endlessly. It doesn't shoot at me, and shooting at it (or for that matter, the white tree that I supposed to be the Shub Niggurath) doesn't produce any effect (or should I keep on shooting them?). What is the ball?
