Simple game based on Google Maps

This is a proof-of-principle experiment I made trying to build a simple game on top of the Google maps API.

You are a farmer trying to get a fox, a chicken and some corn from the south side of the river Thames to the north side. You can drag them each one at a time but you must not leave the fox with the chicken nor leave the chicken with the corn.

I accept that there are some problems with the premise of the game. What would a farmer be doing with a fox? Wouldn't he just kill it? What are they all doing in London? Couldn't they just hop on a number 45 bus over Blackfriars bridge and be done with it?

It's amazing what can be done with the Google maps API. Check out Tom Scott's Real World Racer game.
