One pitch a day: in August of 2011, I dedicate twenty minutes each day to writing an "elevator pitch" for a story or a game.
The action takes place before men learn to make fire. The player takes control of a tribe of Homo Erectus. During a storm, lightning strikes a bush which begins to burn. One of our bold ancestors brings a firebrand back to the encampment. His or her clan begins to tend this flame which keeps beasts at bay but bites any who would come too close. Challenges include rainy or windy weather and lack of wood.
The player wins the game if the tribe learns to make fire before its lightning-made fire goes out.
