Ninja Shape, by Pavel Galchenko, Andrey Tyufteev and Boris Strekalov, is a physics puzzle about something we're all familiar with... being a ninja, who is also very lazy. While mastering the ability to turn from a square to a circle and back again with just a click is pretty impressive, it's not really enough to take out the bad guys, who are doing bad-guy-type things, like loitering around with cigars and squinting... menacingly. Good thing your environment has so many useful things to help you land on them to bust them up, all without moving a muscle! Click our hero to transform them between circle and square, and objects in your surroundings to manipulate them or turn them on and off... dynamite barrels and crates can be triggered to destroy brick, for example, and handy suction-cup machines can push and pull anything in front of them around the level. Grab all the stars scattered around each stage for a perfect score! Ninja Shape isn't exactly a new idea... games like WereBox and Golden Scarabeus have played with the same concepts and mechanics, but that doesn't mean Ninja Shape is any less enjoyable... or cute! Its mechanics are well implemented, and offer enough variety to keep you on your non-existent toes, though the fact that you sometimes don't immediately shift between shapes when you click can make for frustrating times in area where timing is called for. Still, Ninja Shape is a fun little break that's just the ticket for when you're feeling like a square. Or... circular. Whichever.
