Friend or Foe?

It's on online multiplayer 2D platformer side scrolling game. The player doesn't know what to do when the level starts and he will try to get to the end of the level. When he reaches the end of the level he gets his objective or he can find hints during the level to try and understand the objective before he reaches the end. Every level has random objectives and controls so you never know what to do.
