Colorful infection is coming! Jump into a world filled with marbles, rotating stones and a lot of thinking. Patience is needed.
As the name says, you have to infect yellow stones using the brown ones. Just touch them and it’s done. But the marbles can move only as the ground allows so the path is mostly harder than the goal. Make the bigger, smaller or rotate the platforms. It’s nice that you can ignore some levels if you fail too much.
