Once again this really isn't intended for AI, but some do work depending on what island they start on... Rat will work on every island, as far as I can tell.
This really is a fun map to play... lots of action even in just the first minute of play!
The outer islands have more oasis available to them which makes it easier to play, but for the real challenge play on one of the center islands... This is somewhat challenging even playing with rats and snakes, because there really is no available oasis.
