Twist to the right, slide it down, shimmy to the left, and launch! It's not the latest dance craze that will make the Macarena obsolete, it's how you play Clockwork by Mr Beud, a unique puzzle with a bit of a physics edge where you must pick apart a series of rotating and sliding puzzles to free the gear at the center of... Wait, whaddya mean the Macarena's already dead?
In each level, you'll find a tiny golden gear in a black container, and a mess of beams, blocks, and curves. Beams can be moved back and forth with the [up] and [down] keys, while curves can be rotated on their tracks with [left] and [right]; blocks can't be moved. Your goal, by jimmying the beams and curves around, is to create a clear path above the golden gear. Once you've shuffled all the debris out of the way, hit the [space] bar to launch the gear to check your solution.
The tricky bit to each puzzle is considering that when you slide or rotate, all of the associated pieces will move at once if they are able. A lot of puzzles need to be solved by moving a beam into the path of a curve, such that when the curve is rotated, its path is blocked, but other curves continue to rotate independently (or vise versa, with curves blocking beams). Factor in that some of the pieces may move at different speeds, and you've got quite a challenge on your hands.
There are thirty levels to tackle (plus five tutorial levels), all ramping up in difficulty at a pleasantly progressive pace. Later levels introduce such devilish devices as pairs of blocks that pinch together when there's nothing between them (and can't be separated again), meaning you might find yourself restarting a level several times to find the right way to pick apart the lock. If you think you're up for the challenge, grab hold of the gears and get going!
