Gameplay
In this game, two men are sitting down, with a man standing behind them. Occasionally, either of the men may fall asleep. If a man falls asleep, the player must tap him, which will make the man behind them hit him. Sometimes, both can fall asleep, while, other times, neither can. If the player taps a man who isn't asleep, the game will be lost, and the man will be upset. If the player waits too long after a man falls asleep, he'll descend into a deeper sleep and the game will be lost. The game is won if both men are awake at the end of the game.
