Pairbox

A recursive puzzle game for two. Play on one keyboard, a keyboard and a controller, or two controllers.

Every box is a room you can walk into. Turn a box, and gravity turns for whoever is inside. You can't turn the room you're standing in, so you'll need each other.

Rooms sit inside rooms, inside each other, even inside themselves. Step into a copy of a room and come out where the room really is. Fall forever until your partner turns the world.

• 53 puzzles in 8 chapters, every one checked by a solver to need you both
• Walk and turn: no pushing, no timers, and undo is always one key away
• Stuck? Three puzzles are always open, so you can come back to one later
• An original soundtrack that changes with each chapter, included as MP3s
• English and Chinese

Playing apart? Pairbox is couch co-op. To play over the internet, one of you can host with Parsec and the other joins with a controller.
