(This was a free online game, not a disc or a PlayStation game or anything like that.)
There were two llamas (or something--I can't remember what animal it was), one was pink and one was green, and you first controlled the green one and took him to one exit, then the green one's actions replayed and you had to take the pink one to the exit.
If it helps, I also remember that there was really pretty piano music playing in the background.
