ibb & obb is a cooperative adventure designed for two players. So find a friend for some true co-op puzzle solving fun.

Can I play online?
You can play co-op locally or online. Online you can either invite a Steam friend or match up with a random other player. For a local game you can make use of keyboard and controllers, or a combination of those.

No single player?
Technically you can control both characters simultaneously on your keyboard, but the whole game is really designed around the interaction between two players. On your own it'll be very hard and simply less fun.
