It all starts with the PC sitting on a tour tram through Everglades National Park, Florida. Except for a few obscure references in the introduction to the game and a mysterious item in your inventory, you have no clue at all to what you‘re supposed to do in the game, and until the first puzzle is solved, the PC’s motivations and identity, too, will remain perfectly concealed to the player (though, presumably, well known to the PC).
The first part of the game is all one puzzle. It’s quite possible to put the game in an unwinnable state here: to work the puzzle you need to know a few things about the game world and you also must take precautions against certain (predictable) future complications. The puzzle is not too bad, if you feel for a bit of old schoolish puzzle-working, but it does involve a lot of extremely tedious wandering about in the (labyrinthine) wetlands of the Park.
Then, all of a sudden, the game changes character totally and in almost all relevant respects.

Specifically, the evil Pyth-Nor Real Estate Development Consortium has constructed a giant robotic python, which you and the rest of Gator-On have to engage in combat...
From there on the game is just as weird as that. This concluding part of the game depends heavily on non-standard commands. However, the text of the story generally (though perhaps not invariably) gives you sufficient clues to them.
