There are no fairies in Newtom's Fairy Clay, but there is quite a bit of clay, as well as beautiful purple elephants, strangely controlled lifts, and salami-coveting tentacles. It's an odd but lovely claymation world, and you can point and click your way through short but sweet levels to reach a rather unexpected ending.
The game has a subtle sense of humor to it and delights in absurd or unexpected solutions, which is great from an artistic standpoint but can be frustrating for you as the player trying to figure out what to do next. There isn't really a plot to speak of, not even a basic one like "escape," so mostly you're just trying to figure out how to make something happen. Things that you might think are important turn out to be red herrings that you can't interact with at all, and many of the solutions are things you couldn't possibly predict. Without spoilers, it's along the lines of seeing a chest that needs to be unlocked, and putting down some birdseed in another part of the room, and the birdseed causing a giant bird to come out of nowhere and kick the chest open. When solutions are that random, it's not so much puzzles you solve as it is trial and error.
In general, green means that your clay hero can walk there, and an open hand means you can manipulate something. One object contains multiple hotspots, but for the most part the changing cursor is the most fair part of the game, and enables the player to actually beat the thing. That's fortunate, because the animation, particularly the closing scene, is really charming. If you're looking for a lovely, simple yet surreal break of claymation in your day, then look no further.
