Sugarlawn

The Gaming Philosopher
Fun and educational puzzler, if somewhat disjointed

Let me stress that the game is a lot of fun. Enough fun that I came back to it after the competition and solved everything, with some help from the forum, ending up with a very respectable haul (though quite a bit short of the current high score). If you are interested in puzzle games, I absolutely recommend Sugarlawn. However, the game is also a bit of a disjointed affair.
