The old video game magazine, Electronic Games, has a review of this game in its February 1983 issue, on page 62. It describes the game as being a "three-scenario contest". I read further, and realize there's no description of the boulder scene. There's 2 screenshots of the game showing the river and cannibal screens, so someone there must have played it all the way through. I just don't know how they could forget an entire scene unless the game they played didn't have it. Has anyone ever heard of this version before?
