Jon of RealGamerNewz writes, "ibb & obb is an incredible experience in two player, co-operative platforming / puzzle adventuring which will have you laughing at times, doesn’t require a mic to be enjoyed online, and has an equally fascinating (though slightly less playable) single player game mode. Controlling either ibb or obb, you’ll run into platforming puzzles that will at first have you stumped. Quickly through either trial and error or logical rationalizing, you and your partner will find your way through each level and grow to appreciate the simplicity of ibb & obb’s gameplay design. Figuring out how to use each element of gameplay, which is introduced one at a time, is definitely part of the fun. From jump-pads to character-specific portals you’ll have to master all of these in-game mechanics in order to advance."
