Plith is a fast paced puzzle game which contains a lot of levels - more than 100 - to be solved. The player moves some gears and can place them on the level; some gears rotate, and transmit their rotation to the adjacent ones: the objective of each level is to activate the target gears. These levels constitute five different worlds, which are subdivided into fourteen sections. Each section introduces new gameplay elements; for example, several kinds of gears and obstacles come out along the game. The game is presented using mostly 3D graphics, with a few handmade drawings as well.
