Escape from Ice Station Hippo was originally written to show off a Hugo pathfinding extension, but it joins the ranks of sample games that are entertaining in their own right. The writing is fun, and like his previous work, The Hugo Clock, there is one puzzle that should appeal to those nostalgic for "old school" puzzles.
In the version I originally played, I missed the clues as to what objects I should be looking for first. The game, at the time, was distributed with its own source so this wasn't much of a problem. Since then, I know McWright has finessed the game to better clue the player, but knowing what to do, I've pretty much lost all objectivity on the current difficulty. Just the same, I'd encourage others to try it out and see for themselves.
