No graphics, terrible gameplay.
The fact that this game is entirely text-based hurts this flash quite a bit, but what really destroys it is the fact that gameplay is so incredibly dependant on luck, and does not provide the player with decent information (i.e. requirements for shelter, signal, etc.) or provide opportunities for the player to make real, meaningful decisions. You cannot prioritize finding coconuts over chasing an animal for food, for example.
In short: IT SUCKS.
