In terms of reviewers qualified to take on a game that involves the herding of cartoon farm animals, there are none that come more highly decorated than I. In 1986, my Dad was named Sheep Farmer of the Year. If you can think of a farm animal - any farm animal - then the chances are that he's chased it around a field waving a stick. With these shared rustic genes in mind, allow me to lean over a metaphorical fence and explain just why Flock isn't particularly good - and then add a couple of reasons why you townie types aren't welcome in my gateway either.
Flock sees you control a UFO hovering over sixty patchwork quilt rural scenes, with the quaint extra-terrestrial intention of hoovering up a shopping list of sheep, cows, chickens and pigs. It's a game that's very much of a Lemmings mentality and, for that matter, World of Goo to boot. You must spook your furry charges across each level, herding them around pits, through gates and past various obstacles before finally manoeuvring them into the tractor beam of your waiting mothership. Or, as the game insists on calling it, the Mother Flocker. Because, yes, if you've been waiting for a game to finally make that brave tangential leap between the words 'flock' and 'f***' then you're about to have a field day.
The deal is that sheep shrink when wet, cows knock physics objects over and will stampede if herded too closely, chickens adopt Zelda-esque flapping behaviours when chased off ledges and pigs are spherical and roll around like marbles - which, the pedant in me wants to underline, is most certainly not canon.
