I was three steps away from finishing the game when I got stuck. Did the walkthrough and saw the club/stick was used on the wall but I remembered using it on the rock and then it disappeared. So I thought, it should have been used twice. I started again from the beginning, only to realize there are two club/sticks that are look-alike, each to be used for its own purpose.
I loved the game because it was fun and challenging. There were no interfering commercials, no glitches, and has a resume button. Thanks.
