Unanimy

Unanimy starts as a simple puzzle game about getting a collection of robots to the same tile, while all of them move in sync. Throughout the game's six worlds, the mechanics become more and more complicated.

We start with the basic task of getting our two robots together. They move in sync, you can use the walls to stop them, and if any fall off, you fail the level and must either restart or undo your last move.

Later, we see colored walls. Blue robots are blocked by blue walls, and red robots are blocked by red walls.

Then we add reversed robots. Notice the brighter tone and the inverted colors on the arrows, indicating that when most robots would move right, these will move left.

Eventually, we add green robots. Unlike red and blue which can't fall off or you fail the level, green robots must fall off for the level to be complete.

All the while, you'll be not only solving each level, but optimizing your solutions through the par mechanic, which gives you an added goal on every level to complete it in as few moves as possible!
