Unmechanical is a side-scrolling puzzle game with 3D graphics. The player controls a robot the size of a head that is out strolling around when it suddenly is captured and dragged into the underground. Now it finds itself in a strange and mysterious place full of both mechanic and organic machinery and has to find a way to escape. The robot has a propeller on its head allowing it to fly and the player can move it around in all directions. Interaction with the world is done with the robot's tractor beam that is emitted from its bottom and allows it to pick up objects and pull levers. To progress through the underworld the player has to solve numerous puzzles which can be both logic, physics and memory based. Solving puzzles opens doors and gives access to lit orbs that are used to power different biomechanical devices that are found around the world. If stuck the player can use the game's hint system which shows a pictogram of the puzzle.
