My Free Game of the Week is Magpie, by sunil.
Ahhh, it's a new sunil broughlike!
Sunil mentions on his blog (where he's written a very nice post about this game) that he takes a week off work each year to make a new game for 7DRL - last year he made Mosaic with Corey Hardt, which was one of my favourite games of the year. The year before, he made Escorial, which I also loved. So this is quite a hat trick! Highly recommended.
