CloudKid produced a game called Negative Nimbus for the iPad. This video is an example of the gameplay. With simple and intuitive tap and swipe controls, players will accumulate points by helping Nimbus rain on flowers while keeping other characters dry. Rain on sunflowers to gain multiplier bonuses, use Bill the Umbrella for extra points, and unlock achievements, comics, and lots of accessories along the way.
