In Codroids, you take on the role of a factory manager with a simple job: guiding brightly colored worker-droids to matching spots on the factory floor. A straightforward task, until some bad wiring connected the movement controls of the droids and made them move as one! Pressing "left" in Codroids makes every droid attempt to move left.
To successfully get a droid where you want it, you must make clever use of the factory walls and of other droids. Just beware that in doing so, you will almost certainly mess up everything else.
The game mechanics of Codroids are simple and intuitive, and the puzzles remain small and lucid throughout the game. On average, the levels can be solved in less than 12 moves.
Codroids is, however, very challenging. It just achieves this without presenting increasingly large and intricate levels, or by constantly throwing new game mechanics at you. The solutions are not complex, just easily overlooked.
