Ibb & Obb is a puzzle game where you run, jump, land on enemies and solve momentum puzzles. The novelty is that it's a game designed for co-operation. One player controls the green creature, Ibb, and the other controls the pink creature, Obb. The world is divided by a horizontal line in the middle which acts as a mirror and the point around which gravity reverses.

It sounds complicated but is actually a fun and simple game where you use this gravity flipping aspect, along with the ability to jump on each other or fling the other player off special jump pads, to progress and collect the sparkles.

Fall up and jump down through 15 levels filled with double gravity puzzles and discover 8 hidden worlds that will test your new non-Newtonian skills to the maximum. All levels have their own unique music, composed by Kettel known for his warm melodic electronica.
