Nevertheless, successful play also requires that important features of the scene be verbalized and that plans be made. It is possible to learn from experience and try again. Here Lemmings is easier than the real world, because the exact initial situation is repeated when ever a play is restarted. Moreover, Lemmings is deterministic. The same sequence of actions will always have the same effects.
People formulate in natural language facts about the Lemmings world.
We can expect to devise formal tools of equal power. Besides facts, people tell each other lemming stratagems, both local and global. We will not try to formalize the physical skill of making several moves accurately and in quick succession. In the actual game, vigourous use of the pause facility can avoid much of the need for practicing fast reactions.
