The hero of the game deicides to go on a walk through the forest, when he is suddenly cornered by monste. The monster wants to eat the hero... because that's how video games work.
Monsters are known to give chase at full speed for a short time before they become fatigued and must slow down. This is the key to the hero's survival: learn the pattern of the monster's fatigue level, and the hero will survive.
The hero has lived a life of luxury and has never taken fencing lessons, therefore he is unable to fight against the monster. His fear level gives him a greater level of stamina than most of the monsters, however he will soon become fatigued if he constantly runs away from the monsters. Remember, hero, you must take a rest every so often.
