Excellent Experiment
The best games of the indy-games circuit are the "experimental games", and I'd say your game definitely falls under "experimental gameplay".
As it stands alone, the best praise I can give it would be to call it "artistic expression of a scientific observation", though I would leave it up to the player to determine (based on their end result, nudge) what that observation entails.
It would make a great engine for any number of games that call for or play upon the elements involved. I don't think I've ever seen a crowd simulation that convincing in a game before. And the symbolic communication is really great, it avoids complexity where none is needed.
I think it will be remembered and played for a lot longer than people have been projecting, actually -- unless they read this and it convinces them to do otherwise? Hmm!
