Mushbits

There are two bunnies in the board, one is blue and the other is pink, they can only cross on platforms that match their colour, and whenever they cross over a normal platform, it changes to the opposite colour beneath them.

Click on a rabbit and drag over the floating squares to create a path, then release to watch the rabbit hop merrily along it. You can take as many moves as you like to try to complete each level, though the only way you'll win a gold star will be if you do so within the number of moves in the top-left corner.
