Gravity has turned into a long line of wibbly wobbly gravity wavity stuff and ibb & obb are here to get to the end of it.

Released in 2013, ibb & obb is specifically designed as a two player cooperative platformer game set in a puzzle filled world where gravity goes both up and down. You need to work closely together in order to succeed and you can play in either local co-op or online co-op with a friend.
ibb & obb travel through a world divided by a horizontal line - above the line gravity goes down like normal, but below the line gravity is reversed and pulls you back up. Momentum is conserved and the world is filled with enemies and objects, which leads to a number of interesting puzzles and scenarios for ibb & obb to work through.
