Team up

Communicate with your teamate
to find your way through the game

Level up

Complete the levels and go as deep as you can in the game. The increasing difficulty should challenge even the bravest !

Cooperation is the key

Remember, you are not alone ! You have to work with the other player to meet him at the right place at the right time.

Sequential input

Unlike most of the games, you have to decide what path you will take before seing the consequences of what you have done. This way of thinking is also the way programmers build the softwares and websites you daily use !
